I've got Windows XP running on Bootcamp on my 15" MBP, with a 20" external monitor hooked up via Mini DisplayPort --> DVI. I'm trying to keep the monitors independent of each other (not have mirroring on) and be able to launch games full screen on the external. Right now I'm trying to get it working with the Steam games (Portal, TF2, etc). I can launch the games in windowed mode and move them over, but then I'm unable to maximize. I tried searching around for information as to how to get applications or games to launch full screen on an external monitor, but haven't been able to come up with much. I'm hoping someone here can shed some light. Thanks!
