Why does photosynth keep closing my browser??

It doesn't just crash on pages with synths on them, it crashes on almost all of the pages. I do have Silverlight 3 installed: the browser crashes on both of the silverlight web-pages you listed, and crashes on the 2nd, 3rd and 4th videos (the first video and last two play alright).

What do you suggest?
And thanks for helping me with this :)

Full disclosure: I'm just your fellow user, so hopefully someone official will chime in here.

All I know so far is that your specific computer is having some sort of problem with Silverlight, but it's difficult for me to pin down since I don't have the same problem, nor have I heard of anyone else reporting it.

I am highly interested in the fact that the Channel 9 video player (the big ones) works alright for you but the Channel 10 videos crash your browser. I'm sure that tells us something important but I'm not sure what it is. (You are saying that the bigger video players play the video here on this page, right? - not launch the video in a new window?)

I'll keep thinking it over. In the meantime I guess I'm wondering whether you have Internet Explorer 8 installed or if you're using an older version. I assume that you have Firefox 3.5.5 installed since it tries to update automatically.

If you don't hear back from someone here soon I would check over on the Silverlight help forums since it seems to be a Silverlight problem - more widespread than just the Photosynth viewer.

As a last ditch effort you could try the older Direct3D Photosynth viewer. If you use the same username on Photosynth.net as you do here on Get Satisfaction then I believe that this should be the link straight to the Direct3D viewer for your first synth:
http://photosynth.net/d3d/photosynth....

It requires that your computer have all the appropriate software installed to run 3D graphics (Up to date DirectX, up to date drivers for your video card, hardware acceleration settings in Windows set to full, etc.) which gave so many people problems that they changed over to Silverlight which is just one small single installation that doesn't bother with your graphics card at all. By and far the Silverlight viewer has been a huge improvement in getting things to work for people right off the bat but unfortunately not in your case. Anyway, try it and see if it works and I'll keep looking for an answer to your Silverlight problems.

I don't suppose you get any specific error messages when your browser crashes? It would sure help to have those in front of me if there are such things.

Yeah the big videos play here on this page (they don't launch in a new window).

I am using Firefox 3.5.5, but until this afternoon was using Internet Explorer 7 and now have 8. The issue is essentially the same, but appears slightly differently as instead of the browser completely closing when trying to navigate to a problem page, the tab will wait a little and then go back to the page I was viewing before, with a message saying that the tab crashed & re-opened (so I still can't actually get anywhere because I keep ending up back at the same page).

I tried the older Direct3D viewer, and it did let me view my synth, but again navigating away from there caused the same fault - so it must be a silverlight problem.

And unfortunately no, I don't get any specific error messages - not even the "not responding" or "end programme" messages I would usually get if a programme crashed. The browser closes just as it would if I had closed it, except it happens automatically!

I'll try in the silverlight forums :)
