Quoted from my thread over at Apple Discussions: Thread Link
If somebody here can help me you'd save me a trip and bugging/arguing with an Apple Store genius.
Apple Thread said:After reinstalling Tiger today anytime I open Photobooth or try and use my iSight in iChat I get the "iSight is in use by another application" error, yet I've restarted, repaired permissions (doubt that helps) and closed everything multiple times.
I really can't afford a trip to the Apple Store so if I'm missing something could somebody please help me out?
