Update your graphics driver.
Thanks for the suggestion, I went and updated them to the latest Nvidia drivers. I have the Quadro 4000 2GB 256bit. Still no luck, I am having the same problem. Good idea though, I hadn't thought to check that.
Any other ideas?
Spent 2 hours on the phone with Adobe, problem resolved. We think it was caused by a corrupt install conflict with the previous version of Master Collection 5.5 that I had installed. After a clean install and some playing around with the registry, and deleting anything related to adobe on my system, the problem seemed to be resolved. However....
Problem came back 2 days later. The only thing that had changed was, I was running Synergy to control my mac with my PC. Uninstalled Synergy, problem resolved.
Had the same issue recently, it also affects the Rotobrush pretty badly. I've uninstalled Synergy and everything worked super. Still happens with Synergy 1.4.15 on Windows 7.
