For example, I am unable to launch a gui for our backup program, netvault, gui is "nvgui". It simply flashes, and dies out. That was on day one.

If I "shake" a window, it leaves its traces all over, and there is nothing I can do about it but kill the session again and retry. Any ideas?

I have FreeNX on my server now and NX Client from Nomachine on my 
XP desktop.  However my ssh is configured for PW access; not Key 
access.  My ssh clients work - that is I have access to the 
server.  However I cannot gain access via the Nomachine client.

My plan was to get FreeNX working with the password security 
first, and after that change the Nomachine client and the other 
ssh clients to Key access.  But I am stuck at the moment - not 
sure how to trouble shoot my inability to get access.
