Hey everyone, I have a rev c imac g5 with built in isight. Recently i have been using it to vid chat over aim. However when i click on a persons little green simble to start a chat my mac freezes for around five seconds before even showing my video. Does the same when looking at ichat prefs - there is a corresponding CPU spike as well. No other apps like photobooth etc have issues accessing the isight there all instant - any ideas?
