Except it doesn't. I never used to have X11 forwarding problems with 
SSH, but I just went round and round with this problem this evening. I 
gave up and noticed this thread.  Forwarding that used to work no longer 
does. The application just seems to hang. And there is no error logged 
anywhere that I can  see.

In the past if X11 forwarding was turned off at the client or server, 
the DISPLAY variable was not set. The DISPLAY variable is set, all of 
the config files (server and client) allow X11 forwarding.

This is odd.
