Remotely run GUI shows up incorrectly on Cygwin 1.7.1

[Dan Sandberg <dan dot sandberg dot lists at gmail dot com>]

Hi,

I recently upgraded a computer running XP Embedded to Cygwin 1.7.1.  
When I ssh from another computer, and run a graphical program (such as 
the calculator included in Win XP), it doesn't display correctly.

If I run the program from a local ssh shell, it does display correctly.  
Here's a picture which shows both a locally run instance (bottom left) 
and a remotely run instance (top right).

I have given the sshd service permission to interact with the desktop.  
I downgraded to Cygwin 1.5.5 and didn't have this problem.

I tried de-installing and re-installing the service with cygrunsrv 
--remove and --install, but it didn't help.

Anyone have any ideas?  Perhaps a bug in the latest Cygwin?

Thanks!

-Dan
