RE: Xt error:can't open display;ssh not passing $DISPLAY

["Dawson, David W" <david dot w dot dawson at lmco dot com>]

BTW, since "127.0.0.1" is the loopback address, setting a DISPLAY value of
"127.0.0.1:0.0" tells a client to talk to the X-Server **on the same machine
that it is executing on**, which is certainly not your PC.

John,

Didn't you think for a moment that something of infinitly more 
importance than the contents of various config files would be the actual 
command line that you are using for ssh?

Post the command line that you use to ssh to your remote machine.  You 
do know that you have to run ssh from within an xterm in your 
Cygwin/XFree86 X server, right?
