This was the problem that a child of menu bar shared (forcefully) its
UVALUE with the menubar and the rest of menubar children. I think I
reported this for version 5.0 and was assured that such behavior was
beneficial for me. I forget what the explanation was, but I had no other
choice but to use buttons as top-level items on menu bar. Their Uvalues
were all the same, but you never use them. Menu items then could have
different Uvalues and be used in the most conventional way in event handlers.

I still use buttons as "insulators" between menubar and droplists of
menu items. It does work, although I am not sure if it is necessary anymore.
I use IDL 5.2 on a Mac. BTW, I have no system crashes when messing up
with widgets, including menu bars. Might be that faulty MacOS release,
you never know :-(
Cheers,
Pavel
