I'm using my iSight with Yahoo Messenger but after 10 minutes the video freezes up. The camera i still working since I can hear how it focuses if I put the hand in front of it. I have to quit the app and realunch for the picture to come back, then my friends need to select "View WebCam" again. Kind of frustrating. iChat does not seem to have the same problem. I'm on Panther and a Cube. Has anyone else experienced the same problem?
