Hello all. Steve Wright asked me to pass along these experiences. I  
was testing login to the HPC to help out another faculty member.

1. After I first requested my account via the web, I could not login  
via ssh without X11. My connection was always "reset by peer." After  
I had logged in once via X11 and "ssh -X", I could then login via ssh  
without X11.

FYI, I didn't wait the 10 minutes to try to login, so perhaps it is  
just coincidence that logging in finally "took" when I tried ssh -X.  
But I do know my password was registering, because I would be told to  
try again if I intentionally mistyped my password.

2. Via X11 in Mac OS X 10.4.6, I cannot get Matlab to draw properly.  
Only the upper left corner is drawn, about 1 inch down and 2 inches  
across (I can see the first 3 letters of the Windows menu title).  
Reaction to clicking on a menu title is very slow also.

Using Matlab with Cygwin/X seems fine.

3. Via both Mac X11 and Cygwin/X, the application xstata crashes as  
soon as I click on a menu title. The program quits with the error:

Gdk-ERROR **: BadWindow (invalid Window parameter)
   serial 2002 error_code 3 request_code 38 minor_code 0
Gdk-ERROR **: BadAccess (attempt to access private resource denied)
   serial 2003 error_code 10 request_code 102 minor_code 0

Hope this helps you get the bugs out. -Dennis
