Help! Yesterday my Macbook Pro was fine, completely fault free. All of a sudden, when I turned it on today, I noticed that the green light beside my built in isight was on as soon as I pressed the power button. It would not turn off, even when in mac osx, and I checked and made sure that no applications using isight were running (widgets, photobooth, etc.). As well, I alread tried restarting. Furthermore, when I open photobooth, I only get a blank green screen, and isight is now unusable! What has happened/what should i do! Is there any way I can fix this? is this a known issue? HELP!!
