Whenever I try to snap a photo in Photo Booth, PB locks up. I tried reinstalling the software but no luck. Video chat works fine so it's gotta be something with that software on this hardware. Any suggestions? Am I just going to have to lug my new computer back into the Apple Store? I'm on the 21.5" i3, 3.2 ghz machine. Running Snow Leopard (of course). No hardware modifications to the machine.
