Photoshop CS5 and Crashing With OS X 10.6.4 with ATI Radeon 4870 and OpenGL on Mac Pro

Causing consternation among Photoshop CS5 users, CS5 apparently crashes with the ATI Radeon 4870 video card on the Mac Pro. The problem apparently affects Adobe After Effects also.

Read my related discussion and suggestions in the MacPerformanceGuide blog. My general advice? Turn off OpenGL— it causes problems and makes screen refresh slower.
