Launched in early June, the plug-in provided a way to run Microsoft Outlook on Google Apps instead of Microsoft Exchange. Sadly for Google, the plug-in didn’t play well with Outlook, most notably making its data inaccessible to Windows Desktop Search. Now, after a few weeks of troubleshooting and some help from Microsoft (that must have made for some interesting conference calls), the company has found a solution to the problem and a fix has been released.

“We worked closely with Microsoft to address two issues that we shared recently, and we appreciate their help,” Google Apps Senior Product Manager Chris Vander Mey said in a company blog post Tuesday. “The Windows Desktop Search feature now works, so you can choose between the native Outlook search, which has been available since launch, and Windows Desktop Search to find information in Outlook.”

With that little snafu resolved, it’s now back to business for Microsoft (MSFT) and Google (GOOG), with the former attacking the latter’s search business and the latter steadily encroaching on the former’s software turf. We now return you to our previously scheduled hostilities…

Internet navigation browser plug-in maker Cooliris, which lets users “see” media on the Web in a more visual manner, has gotten $15.5 million in additional funding from its investors.

The new round includes Kleiner Perkins, Cooliris’s initial investor, as well as DAG Ventures, the Westly Group and T-Mobile’s T-Ventures.

Cooliris had already received $3 million two years ago from Kleiner.

The Palo Alto, Calif.-based start-up is also releasing the latest upgrade to its 3-D “wall” software out of beta, which adds more online content from around the Web, including from social-networking sites like Facebook and from a user’s own hard drive.

The trend toward making the Web browser look like a television screen and navigating information more visually is increasing all over the Internet, from video services like Boxee to visually-oriented search services like Searchme.

“We’re trying to allow users to discover, navigate and consume more of the Web in the same amount of time, using visual means, than people do now through text links,” said Austin Shoemaker, Cooliris co-founder and CTO in an interview last week with BoomTown.

Launched last year with a plug-in called PicLens, Cooliris said that its software had been downloaded 10 million times and that it has three million active daily users. It also has a popular iPhone version of its software.

Here are two more Cooliris screenshots like the one above (click on any of them to make them larger):

As you may recall, Tesla sued Fisker Coachbuild back in April, charging that founder Henrik Fisker stole valuable company design ideas and trade secrets after it hired him to design the company’s oft-delayed plug-in electric-powered WhiteStar hybrid sedan.

Tesla claimed Fisker sabotaged the WhiteStar project by purposely drafting a subpar design that set it back three to six months, then stole proprietary Tesla technology and used it to build a competing car–the Fisker Karma. Unveiled at the Detroit Auto Show this past January, the $80,000 Karma had been scheduled to arrive at market in late 2009. Because of the production delays allegedly caused by Fisker’s designs, the WhiteStar won’t arrive until 2010.

“I think it’s ironic that Fisker chose to name his car the Karma, when what he’s done is very bad karma,” Tesla attorney Adam C. Belsky said back in April.

The arbitrator, it seems, didn’t quite agree. “The evidence is overwhelming that Fisker did nothing wrong,” he found. “The assertion of violations of the Uniform Trade Secrets Act by Fisker were baseless and neither brought nor pursued in good faith.”

A tough break for Tesla, which has been hit hard by the financial crisis, so hard that it was forced to borrow $40 million to cover its costs earlier this week.

While rumors of its impending re-sale have apparently been greatly exaggerated, what’s true about StumbleUpon is that its new Web-centric look and feel and a new partnering program represent a major shift for the online discovery service.

The San Francisco-based company, which was founded in 2001 and sold to eBay last year for $75 million, is announcing tonight that users will no longer have to register or download its toolbar to “stumble” the Web.

Users can now simply start on StumbleUpon’s site, for example, and stumble all over the Web using their Web browser as guide rather than a toolbar.

The move is being made simply because most Internet users are increasingly loath to install Web plug-ins like toolbars, a requirement that naturally has slowed the growth of StumbleUpon’s service over time.

Currently, StumbleUpon has about six million registered users, although only a fraction of those are responsible for the approximately 12 million daily “stumbles,” all using a toolbar.

“We wanted to attract users who do not want to use a toolbar, making it easy so they could use the service right from the get-go,” said Garrett Camp, co-founder of StumbleUpon, in an interview with BoomTown earlier today.

Camp noted that that the toolbar–which has been downloaded between 11 and 12 million times–has seen that growth slow over time. Nonetheless, it is not being eliminated either.

“[Toolbar adoption] was still growing, but not accelerating,” said Camp. “Being able to stumble without one was the biggest feedback we got from users.”

Along with the Web-stumble change, StumbleUpon is also unveiling a redesigned homepage–see an example of it below; click on the image to make it larger–which is an attempt to make it more of a destination.

With the new look, visitors can find content by topic and more related to interests. Other changes include a new look for profile pages, as well as user reviews, rating and comments.

Along with its distribution shift and site renovation, StumbleUpon is unveiling a partner program called StumbleThru that will allow visitors to discover content within those sites without going to StumbleUpon.

Sites–starting with HowStuffWorks.com and the HuffingtonPost.com and followed within weeks by RollingStone.com and National Geographic–will display a StumbleUpon “badge” or custom widget.

It is not unlike similar buttons that now dot Web pages from news discovery services like Digg, which users can click to find related pages.

Essentially, much as Google (GOOG) delivers custom search within Web sites, StumbleUpon is offering custom surfing, giving publishers StumbleUpon technology to allow its users to surface content within their sites that is often deeply buried.

As to the blog reports that eBay (EBAY) had put StumbleUpon up for sale after owning it for a little more than a year, Camp essentially dismissed them, noting that the unit is still operating as an independent subsidiary of the auction giant.

“They have given us a lot of runway,” said Camp.

Here is the new front page of StumbleUpon:

Also, here is a video I did last year at the exceptionally noisy (sorry!) party that StumbleUpon threw after it was sold to eBay a little more than a year ago:

This week I tested SeeToo, a free service that lets you share videos in the same time that it takes to open and watch them on your own computer. Even better, you get to watch the video along with the people with whom you’re sharing it and type comments to each other in real time.

SeeToo works when one user selects a video to share with other people, who get an emailed hyperlink to SeeToo’s Web site, seetoo.com. After opening the link, these people join a SeeToo session during which everyone can watch the same video at the same time.

With SeeToo, you and your “buddy” can watch and chat about a video at the same time.

While the video is playing for the group, each viewer can pause, rewind and fast-forward the video. A space below the playback screen allows friends to send instant messages to one another during the session. There aren’t any limits to the size or type of video file that is shared, and other types of media — including music and photos — can also be shared on SeeToo without size restrictions.

SeeToo sounds too good to be true, and in many of my tests, it was. The service became available to the public in January in its beta, or test, stage. But I’ve used many other products in beta that were in better shape than SeeToo. And there is one major catch: Once a video-sharing session is over, the participants, other than the person sharing, can no longer access the video.

People who are invited to watch videos on the service can do so using any popular Web browser (Internet Explorer, Firefox or Safari) on Windows (MSFT) computers and Macs (AAPL). But the person actually supplying the video and initiating the sharing session can use only a Windows PC. The initiator also must download a browser plug-in, which seems old-fashioned in the world of Web-based applications. And sharing sessions time out after 15 minutes of inactivity on the initiator’s side, after which point the email link doesn’t work.

I was able to successfully initiate a SeeToo session using Firefox and Internet Explorer on an older Windows XP computer but had trouble with two computers running Windows Vista: Neither worked with SeeToo using Internet Explorer and only one worked using Firefox. SeeToo says this is due in part to Microsoft’s new Service Pack 1 for Vista, and the company claims it will have this problem fixed by today. I also had trouble with the sound.

The concept behind SeeToo is also somewhat limiting. Some people may not be able to watch a video exactly when someone else wants to watch it. Some might rather watch videos alone than with others. And typing out back-and-forth chats while videos are playing could be somewhat of a distraction from watching the video.

I tested SeeToo by sharing video with family and friends and watching video they shared. My sister and I got a kick out of watching video footage from a wedding I attended in October. I shot the video using an inexpensive, low-resolution Flip Video camera and the footage looked pretty good. But SeeToo’s site shares video on a rather small screen, and we both wished it were larger.

We sent instant messages to one another in a small space below the screen, making comments about the guests’ dance moves and the DJ’s choice of music. I used on-screen tools to pause the video when the camera passed by a friend whom I wanted my sister to see. To take a second look, she selected her screen’s Take Control button and rewound the footage to see my friend.

For the first two seconds of a video, users can see a small image in the top right corner of their screen that displays what the other people are seeing. SeeToo explained that this is a way of confirming one person is indeed seeing the same screen as another person.

I originally invited three people to watch the video with me. One friend I invited was at work, where his computer restricts him from watching videos. When he got home that night, the email hyperlink didn’t work — nor did it explain that the session had expired. Instead, it crashed his Firefox browser. I also invited my boss to watch the video with me, but he only saw my invitation two hours later when the session was over.

I didn’t even try to invite my parents to see the video because neither of them sit in front of a computer all day long and they wouldn’t have received my invitation in time to see the video.

In some ways, it was probably better that the other people I invited to watch the video weren’t able to see it, because the instant-message chat screen currently labels everyone as “buddy,” without distinguishing one person from another. SeeToo hopes to change this in future versions of the service by offering users a chance to register, thus receiving a specific nickname for chatting purposes. As of now, no one who uses SeeToo needs to enter any personal information such as a name or email address, which is a plus. SeeToo is also ad-free as of now, but the company plans to monetize parts of the service sometime this summer.

I also shared music and photos with friends using SeeToo, but this feature isn’t obvious; the site is primarily focused on sharing videos. Music playlists can’t currently be shared with friends, nor can photo slideshows be shared. Instead, individual songs or photos must be selected and shared within a session, one at a time.

SeeToo has high hopes of adding many features in the future, probably by June. Those features include a full-size, higher-resolution viewing screen for sharing and watching videos; a fully Web-based, download-free version of SeeToo; photo slideshows; using names to distinguish viewers; and sharing sessions that don’t time out. In addition, it hopes to let Mac users initiate sharing sessions. The site aims to be out of its testing stage by September.

Right now, SeeToo can come in handy if you know someone else is at a computer and ready to watch a video. The invited guest never downloads anything and neither party needs to register to use SeeToo. But its screen is a bit on the small side, and the service needs to become more versatile before it can be seen as a reliable sharing site.
