It looks like I have a choice. I can have a Vista installation that works for everything except OpenGL games, or I can have OpenGL drivers that work for everything but Aero/Glass, and crash Vista when I shut down my machine.
Vista came with drivers that work for my video card, but OpenGL performance is approximately 1 frame per second (possibly lower - no I'm not exaggerating!) I've tried my laptop vendor (Acer) and video card vendor (ATI). While newer drivers are out for the video card, Acer hasn't bothered to update them (the laptop's about a year and half old, so why should Acer care) and will likely not be doing so at all.
I downloaded third-party drivers from Guru 3d (OmegaDrivers still hasn't put out a set of 32-bit ATI drivers - :cry: :cry:). They work (as far as making my programs work), but the ATI control center crashes, and when I shut down my machine, it blue-screens.
I've tried even a fresh install of Vista at this point. I think I'm out of Vista options. It looks like I'll have to switch back to XP until OmegaDrivers comes out with a set of drivers that work. Perhaps I'll drop him a note asking nicely.
