I have version 2008.1.33c which theoretically resolved a problem with Windows 7 & and Windows Vista. However, I am having that same issue:

The issue is that the screen turns purple after a certain number of images and freezes. We can't save data. A restart of ML often solves the problem-- unlike others similar problems, however, we are able to restart the computer and our long ML program (202 trials) is then able to run all the way through. Help?
