Recently my CS6 has exhibited a weird behavior--when I open a jpeg, for example, only half of the file is displayed--the other half appears as a blank area in the file display area. When I click on the blank space, the rest of the file will appear. Windows 7 up to date, 9 GB Ram, i7 processor. This just started a couple of weeks ago and I have no idea what's up. I've been considering uninstalling and reinstalling but fear for my plugins and understand that reinstalls are not straightforward. Any ideas???
