I am writing a GEM application based on a dialog box which
occasionally has another dialog box written over it.  When this
'pop-up' dialog box is done and I have called form_dial() the second
time, instead of the original dialog box being restored, the desktop
background is restored.  Obviously, that doesn't 'cut it'.  Is there a
way for me to save the background and restore it when I'm done with
the 'pop-up' dialog?

It looks like the problem is that GEM is not aware that my original
dialog box is the background.  How do I notify GEM that the background
is not the original desktop?  I've thought about doing a 'wind_set(0,
WF_NEWDESK, ...)' but, if I do that, how would I get the original
desktop back when my application is done?

Maybe insanity is the best answer.  Any suggestions otherwise?
