I gave up. I downloaded the FrmRemoveObject from Palm and rewrote it to fix
the bug. It took me about 20 minutes and it seems to work.
If you need the code at some point let me know.

Subject: RE: FrmRemoveObject runtime error
You know, I was thinking about this last week, and I got this kind
of intresting idea for installing and removing dynamically installed
gadget objects using a couple of stacks or pointer arrays. You could
basically store the gadget's pointer onto a stack when you're installing
each gadget, then pop the pointer off the top to uninstall it. To give
it a random flavor, you could pop the pointer off and store it in another
stack, and keep "shuffling" the pointers over (deleting the gadget objects
as you go) to that one until you got to the pointer to the gadget you
wanted, pop that and remove it, then "reshuffle" everything back (and
redraw the gadget objects) onto the original stack. To make this seem
more smooth with a large number of objects, you could redraw them in an
offscreen buffer and when you're redrawing, you'd just reinstall each that
way.
It's a bit overheady, and I haven't tried it, but it sounds like it might
work well.
