Also, notepad can't paste while the X system is in the "hung" condition. Once it's killed, paste in notepad returns.

I can send you the "Dr. Watson" error reports generated by Windows when it kills the "Non-Responsive" app - if you would find them at all helpful.

>Only the X System hangs - not the whole PC. Other apps continue to work fine. However, **while** the X system is hung, mintty loses it's cut-and-paste capabilities. Once Windows or I with /bin/kill, stop the X system, mintty can once again cut-and-paste (without any need to restart the app).
