This makes me really happy, since it means my specific system isn't  
broken!

Interesting, this suggests whichever OpenGL apps I tested, don't  
trigger the problem. Hmmm.

I'll look for these next time, of course.

Urk, an OS downgrade would be tricky for me - i'm doing iPhone dev for  
work, and I think I need 10.5.7 to run iTunes 8.2, to run the right  
iPhone SDK...

Or possibly it only affects 7xxx generation nVidia chips, and Jari's  
8600 is a separate module/sub-module. I don't know enough about  
nVidia's driver architecture to guess that, though.

I could be lazy and use this as an excuse to buy a Radeon 3870 (or  
4870 if I'm feeling rich!). But in general nVidia has been better to  
me than Ati ... though at the moment, on Mac, I would tend to agree  
Ati is looking in better shape.

Regards,
James
