I have to see if something happened to my server, but suddenly I am getting 
JmolData.jar looking for a GUI.  This is the error I get:

-----

---------
This is very strange as the server session this is running in has been running 
as a detached screen session for a couple of days without this problem 
appearing.  It may be possible the screen session was still able to access the 
GUI of the user account the screen session was started in.  I will look into 
that.  If that is the case, we still haven't traced every instance of GUI use 
in JmolData.jar.
