Hi, I just got my shiny new macbook, and I am running into a fairly serious issue (I think) When I try to launch photobooth, with NO OTHER applications running, the application refuses to launch because it says the camera is being used by another application. There is nothing installed that was not originally installed on this system. The camera worked the first couple of times I used the computer, but it is no longer working. I have tried to restart the mac (multiple, multiple times) with no success. Any ideas?
