Only one instance of Xming is running on the Windows XP system.
I am using PuTTY to connect to the FreeBSD system and the other
systems.  The other systems all work.  FreeBSD X11 forwarding does
not work.  It is an off the shelf standard install of 6.2.

Manually setting the DISPLAY variable on the FreeBSD system to
[IP address of Widows XP system]:0.0 will allow it to work but
that's not what I want to do here.  I want it to automatically
forward the X11 session through ssh like it does when connecting
to the FC6 system.
