Then I have some work to do
Both ie 8 and firefox 3.5.7 crash for me. When I click on the link for gmc chat, my browser takes me there and I get to see the page for about 2-3 seconds. And then before I get any video my browser informs me that it has stopped working... I click 'ok' and it closes entirely, including other opened windows.
Deleting cookies and updating java hasn't worked yet. I run windows vista on my laptop... haven't tried any other computers yet, but I could try at my parents place this weekend. Personally I think that something is going wrong during loading of the video, however I'm no expert.
