I had the same problum that Misery_Machine has in vista and xp pro crashing my video driver. I duel boot with linux and dident have any problum with my linux install crashing my video driver so i knew it had to be windows related. When i started using 1440x900 res. on my pc and changed my client to use the same resolution the problum went away. hope this helps in some way.
I am running a AMD_64 with a nvidia 8600 GT PCIE video card. windows XP pro_64 and ubuntu 8.10_64 at this time
have a good day
Gary
