Workspace display problem
Do you have transparency on in your "windows theme" settings - older versions of Maya used to really hate it for me - something about being able to see though the top bar drove it nuts.
It being a gaming card means nothing - its mostly cards with good opengl settings that are better - had real problems with displays and ATI in the past but I`m not getting in to that fight again (I hate them - FYI).
Anyway turn off transparency under color in the theme settings and see if that sorts it for you.
Thanks tt,
Collected wisdom suggests that several areas could be contributing to the problem, I'm learning a lot so its back to basics and review the quality of my system and upgrade if necessary. This takes me way beyond my capabilities so its off to an expert with my machine tucked under my arm.
