Motif widgets are notoriously finicky when it comes to destroying them
and creating them. I've never had any luck with them at all. (The same
code almost always works on Windows machines.)
My recommendation is to come up with a plan that doesn't include
destroying the widgets. Maybe you can just make them inactive instead.
Cheers,
David
