Well, reinstalling didn’t fix the problem. However, I simplified my photoshop file dramatically. With all the adjustment layers it was 1.5 GB and about 300 layers grouped into 70 groups. Now it’s just 70 straight layers and 401MB and seems to be working okay. Strange though the earlier version seemed to be able to handle the giant file whereas this new version obviously cannot.
