My bad.  The "fix" was to one package that used motif, not to the underlying
problem.

But interestingly, that package seems to have figured out what to do to
work around the issue.  We might be able to use this.

http://patch-tracker.debian.org/patch/series/view/grace/1:5.1.22-5/motiflockup.diff

The trick seems to be to ungrab the cursor after the XmCreatePopupMenu call.
We only have one call to XmCreatePopup in Xastir, so a similar hack might
work for us.  Of course, the *real* fix should involve fixing Motif, but 
telling all users of Xastir that they need to hack on the source code for
Motif is probably not a good thing.  Furthermore, we've been harping on
using OpenMotif over Lesstif for years, and most of the patches out there are
to Lesstif.

Anyhow, I'm completely tied up until the end of May and won't have time to
make a VM on which to try this sort of thing.  Anyone else got time this month?
The approach itself seems fairly straightforward (test for motif version in
an #if, make a couple of extra calls after each call to XmCreatePopupMenu).

Should nobody else have time this month either, I'll try to look into it in
the slivers of time I'll have.
