Will Poser ProPack work fine with XP? The reson why i didn't want to install XP was because of compatibility issues with older programs. I even had an instance last night where I was working with a smaller file that I know windows 98 can handle and I just changed the light settings and it hung up again. This all started not from windows 98 but from those dam ungrade patches. Ever since I got Pro Pack I've had troubles.
