Odd, I've never had problems with that on Vista. I have heard of something similar though when it first came out, before SP1 was released.
Had this on Vista32 SP2 as well as Win7 RC1. It's rare, but not that rare, but there is no official solution, and even the unofficial solutions rarely work.
It's a pity too. Because you need 64bit OS for more than 4GB and large mem VGA cards (1-2GB) and XP64 is balls. So that leaves you with Vista64 and Win7-64.
Fuck, when I'm forced to upgrade, I'll probably go Win7-64 and an 64-128GB SSD or some thing.
