I'll wait for you to take a look at it. I was just narrowing down
where the problem was occurring. After I had commented out the
Popdown, then I thought to see if I checked that pointer for NULL if
it would still happen and it didn't. The reason I asked you is I
figured that wasn't the correct solution, but a solution that did
work (give you a hint at what might be happening). I reproduced the
error on MacOS X (crash) and Redhat 7.3 (error).
By the way, this is happening during the destructor phase of
UIComponent::~UIComponent. However, it was so deep in the recursion
of DestroyWidget() that it took a while to even track it down to the
Popdown.

Martin,
I'm seeing a crash when dxui exits. I've tracked it down to the
XtPopdown(this->popupMenu) in TextSelector.C. If I change it to
if(this->popupMenu)
XtPopdown (this->popupMenu);
then I don't see the problem, but I wanted to confirm that this is
the correct fix. On other platforms, I've seen it as an error at exit
listed as--
Error: XtPopdown requires a subclass of shellWidgetClass
Let me know,
David
Hmmm,
You may do this if you like. Right at the moment I don't have a build,
but I'll do one and take a closer look. A quick glance at the code
tells me that TextSelector::ungrab() can't be called unless
this->popupMenu has already been created. So I guess, I would not
make the change you suggested without first figuring out how
this unexpected situation is arising. I'll do that in a little
while. If you're in a hurry for something and/or don't mind me
checking in over the top of your fix, then sure, go ahead. The
change you're suggesting can't possibly hurt anything.
