After updating, seems that my iSight camera no longer functions. In iChat, the user on the other end had no video from me, nor did I have a preview. In Photo Booth I get nothing but a black screen. The green LED indicator still functions as if the camera was on, but no image at all. I tried zapping the PRAM and resetting the SMU or PMU as well, but with no luck. It acts as if it's functioning properly with the light activating and system profiler recognizes the iSight cam in USB devices. Am I alone?
