Both Photoshop CS6 and Photoshop CC are crashing about 1 minute after opening a file. Even if I just open the file and let it sit there doing nothing, the application gives me the beachball of death after 60 seconds or so. Any suggestions would be helpful, since I'm getting nothing done without Photoshop of some variety or other.
