No problem; I'm posting my reply to the newsgroup, because I think it

Huh?  Not in the example that I posted...

Me neither. :)  It really is more effort than it is worth; and I think 
you don't need it.

That was almost exactly what the code I posted did...  Hmmmph; Here is 
a revision that exits when you click on the "Exit" entry in the 
menubar, WITHOUT dropping down a menu.  I also added a separate menu 
entry that does cascade down, just to show you it can be done.

If this isn't what you need, then I have no clue what you mean; it 
would be best to post your code (or the relevant portions), to see how 
you are attempting to use menus.

I'm making it an attachment, so it should be easy for you to save and 
run it.  Please DO run it, if you haven't, before replying, and let me 
know if it doesn't work as I say it should.

Also, by using the "menu" option of a Toplevel, this code will 
integrate much better with the system you are on, than if you try to 
make your own custom "menubar", using a Frame and menubuttons, for 
example.  On the Mac, for example, this code follows the systems 
menubar conventions (per desktop, not per window).
