Question About Mac Running PC Windows XP

I have a really simple question. When a Mac runs Windows XP through BootCamp, is there ANY program that can't run in the Windows part of the Mac that could run on a PC running Windows?

nope. any program that can run on a PC install of Windows will run on a Mac install of Windows.

Windows xp run in a mac through bootcamp is no different than any other windows xp running computer. There shouldn't be any problems with software compatibility.
