Adjusting Edit Menu items

Thanks Jacque, that's sounds good but couple of questions.

You gave me the advice about locking/unlocking menus a few months back when
I was trying to manipulate the File Menu so I do have a menu group
mouseDown handler in place.

I discovered then that there's a problem with those group mouseDown
handlers on a Mac - it's impossible to tell which menu was clicked because
"target" and "me" both return the name of the menu group, not the menu that
was clicked, so you end up adjusting menus when they don't need adjusting.
 To complicate matters more, on Windows, the target does return the menu
button name.

I'll go ahead and add the Edit menu processing to the mouseDown and
hopefully it will be pretty quick.

If an Edit menu item is disabled, does it's Mac command key and Windows
shortcut key equivalent still work?  If not, that would be an issue with
this approach unless I watch for those keys as well as using a mouseDown
handler.

Thanks,


Pete
