I am confused as to whether Windows XP OEM will work with Snow Leopard. Apple tells me I need the "full version" and that some people have made the OEM version work but they do not know how. Bootcamp allocates the appropriate drive, instructs me to place windows in the drive and proceeds to run thru the software loading and gets to a screen which asks if I want to proceed with "Setup" then hit enter---problem is the keyboard and mouse do not function---anyone ever have a similar problem? Do I need to buy the "Full" (boxed) version???
