popup menu partially works?

[Andrew Miller <amiller@xxxxxxxxxxx>]

I apologize for my earlier post on overlays.  I've since found out
that only a few PC graphics cards support 24+8 visuals and NVIDIA isn't
one of them.

When I run ivview (or any other app with a FullViewer) I find that
the popup menu works as long as I select something from one of the
submenus.  If I chose Headlight for instance, or I release the mouse
outside of the menu, the menu disappears but I can never get it to
come up again with another right click.  Adding a printf to
SoXtFullViewer::popMenuCallback, I see that it isn't called anymore.

I've done some digging in LessTif but I can't find the source of this
problem, and their popup menu tests work as they should.  Has anyone
else seen this problem?

Thanks for your time,
