Athlon XP 1700 with a gig of PC 2100 and Win2k Pro, SP-2. Vue handles just fine. I also can't use Open GL, but this is an issue with the Nvidia 4in1 drivers, not the OS. If you are getting the SP-3 version, I would suggest a good firewall, as SP-3 has that little addendum in the EULA that says you agree to allow MS to access your system, add, change, or remove at their hearts content. Not on =My= machine, they're not.
