If your editor is crashing and closing without producing a crash reporter window try using Windows Event Viewer to see why Windows is causing the crash. You can follow the information in this Wiki I set up a while back. It will help you find the error code for Windows and then you can Google and investigate why it’s happening.
In my experience with most of these issues, it’s not usually reproducible on our end and comes down to the end-user resolving an issue with their own system. It may be helpful to post an AnswerHub with the details of the crash and the Windows Event log to get further help from our Support staff, though.
