WS=> Thanks for the information.  I didn't say in the subject line that 
the computer froze, just critical parts of the Mate desktop.  The input 
the mouse _and kewboard_  stopped working.  I couldn't use the mouse to 
click on anything and the keyboard input didn't work also.  Even [CTRL + 
ALT + Delete ] didn't work.  Usually this will bring up the restart, 
shutdown menu.  Even this desperate action didn't work.

The problem did not appear again so I hope it was an anomaly.  If it 
happens again, I'll try to use your suggestions.
