Screensaver via Demo - what am I doing wrong?

Hi all,

I'm not sure if I'm doing something wrong, or that my system software
(Win2k) is messed up, or if the Demo version of xatshow has a a
limitation in spite of the information found at
http://www.xat.com/xatshow/index.html

In any case, I can open desktop properties, hit the Screen Saver tab,
and choose the screen saver that I created with xatshow from the drop-
down box... I then hit "Apply" and "OK" and everything looks fine.
However, when I go back back into the Screen Saver tab (again), I
find that (None) is the selected screen saver.

Help?

Thanks,
