Hi all,

Hopefully this works (my last two posts never showed up...). I'm trying to run something on IDL 8.0.1 on someone else's machine, over an SSH tunnel. My code uses PS_START and PS_END to create postscript plots; when it gets to this point, I get errors from the WINDOW procedure:

% WINDOW: Unable to connect to X Windows display: :0.0
% WINDOW: Unable to open X Windows display.
Is your DISPLAY environment variable set correctly?

Why is it trying to communicate with the X Windows display (which I don't think works over SSH tunnels)? I'm trying to make postscript files.

Thanks!
