I'm not going to venture a guess on DRI's motives for the window-limitations,
but I suspect that it was probably easier to code :-)  Does anybody know
whether the REAL GEM (the one that is still supported by DRI -- not Atari's
version) has this limitation?

About putting buttons, editable strings, etc. in Windows (instead of Dialog
boxes):  When I wrote a calculator program, I created a Dialog box with
all these objects.  In my program, I created a window with dimensions set to
the width and height of that dialog box.  Then I displayed the dialog box
inside the window (and redrew it whenever a redraw-event happened.)  The
toughtest part was getting the dialog box to appear in places OTHER than the
center, since that is where these boxes appear by default.
This was done by accessing the dialog-boxes data-structure (and I think
that was a kludge.)

Hope this helps a bit.....BTW, I think this method (of accessing the object's
data-structure directly) might also work for menus -- but I could (and probably
am) wrong.
