Hi Ron,

Glad to see you're making progress. Though some of it
could be simplified by using 'the target' and 'the
selection', it is the way to go for you :-)
Under Windows or any of the Un*xes you could have
moved the 'mouseDown' handler into a 'mouseEnter'
handler ; but as menus are a different animal in
MacOS, that message probably wouldn't be sent (though
I can't check that right now).
