Hi everyone, this is my first post here and i'm not even sure if this is where my question goes. I have recently been using gmail's new video feature to video chat with my friends. It's been working great but recently I can't get my iSight to work in photobooth or iMovieHD...but it works fine in g-chat...any advice?

PS- I checked its USB connection and it says its connected (i think?)

sorry for this stupid question =X hope someone can help!
