XP64 is the bastard child of microsoft which is too bad because compatibility issues withstanding, it’s probably the best Microsoft OS out there right now. Everyone is coding for Vista 64 though and with Windows 7 on the way probably later this year, there’s little incentive for Apple of all people to write any new code for what is essentially, a legacy product. I got a workstation with XP 64 and i have the same issue. I’ll check around.
