what changed? can't run notepad from remote bash session anymore

[David Wuertele <dave-gnus at bfnet dot com>]

When I ssh into one of my older cygwin hosts, I can run "notepad" on
the command line and it maps a window on that host's console.  But
when I ssh into a new cygwin install I made, when I run "notepad" I
can see that the process is created, but the window never maps.

This is true not only of notepad.  In fact, I couldn't care less about
notepad, but the IDE I get from my vendor has the same problem --- on
my new system, I can't cause it to properly run from a remote login.
On the host's console I can run Task Manager and I see that the IDE
(just like notepad) is running but the CPU usage is zero.  The window
is never mapped.  It is getting hung up as if it couldn't find a
display.

I checked my environment and I don't see anything that jumps out at
me.  I'm appending the result of printenv on the command line on the
host that works and on the host that is broken.  Any suggestions?

Thanks,
Dave
