Query: S4-100 Scanner No Good on Windows XP

Don't buy this scanner if you have any interest in the new XP operating system. It only works with the basic functions under the new WIA interface, and does NOT work at all with the included Vistascan software, including the one button functions like copy. Also Compaq barely knows that this scanner even exists, and UMAX (it's a 3400) drivers don't work either.Bad, bad, bad.
