Haven't tried 10.4, don't think I will. Whatever the latest WHQL certified drivers are, 10.3 or 10.3a, they finally fixed the gray-screen/idle desktop crash. I went an entire week running 2D Win 7 without a driver crash, and have gone back to Aero without a hitch for the past few days.
Mouse cursor bug is still there, but I've gotten so use to it that it doesn't bother me anymore.
