I have had my macbook pro 10.6.5 for over 2 years and have never had this problem. But this morning I tried to use my webcam with flash player online and it wouldn't work. I have spent about 2 hours reinstalling browsers, flash player and repairing permissions in disk utility but still no video. The iSight does work in Photobooth and iMovie but for some reason when I select it in the Adobe Flash Player Settings nothing happens. The green light doesn't even go on. Does anyone have any ideas of what I can try next? I am studying abroad in France this semester so do not have my OS installation disks with me. I do have a time machine backup though if that can help. Thanks for any input.
