Problem(s) Encountered:

Was flipping between an IRAF terminal windows when we lost the ability to press buttons on all of the windows. Ended up shutting down the workstation. Was not able to boot it back up, so Eric switched us over the ws2. 

A similar error occurred with ws2, but instead of not being able to press any buttons on any windows, was only unable to click the x  in the corner of any window to close it. Also was unable to type in an IRAF terminal window without it being total gibberish.  Ended up unplugging the mouse and plugging it back in which worked.  Weird.

Solution:

This issue appears to be related to having too many VNC connections running simultaneously.  However, it did also uncover an issue with mdm13ws1.  If it ever needs a reboot now, the local keyboard must be used to strik F1 during the boot process.  Therefore mdm13ws1 should never be reboot remotely, as this will eliminate the ability to reconnect.
