I'd like to get a second monitor to use on my Rev. B iMac G5. http://www.rutemoeller.com/mp/ibook/ibook_e.html I know about the Screen Spanning Doctor. I just want to know what'll happen if I want to play a game just on my iMac's screen. I've tried playing some games at work on my PowerMac and the second monitor turns itself off. If I use the hack will the second monitor just turn itself off on my iMac? I don't run any multi monitor games. Secondly, I've heard some horror stories on getting your registration code for Quicktime 7 Pro. If I reintall Mac OS X will I lose that key?
