I just got a new PowerBook G4 (15" 1.67 GHz model), and I've been playing around with dual displays. I was wondering if there was an option I had to turn on, or any way I can play a full screen game on one screen, and have all my instant messaging, mail, etc. applications on the other? I guess the easy way to do this is do put the game in windowed mode on one screen, but I'd really like it to be full screened. Is there any way around this?
