There's no reason to test for the current menu item values -- RR will 
return the correct menu item name, depending on what was in it when the 
user chose it.  If you had it set to "Stop" then simply call your stop 
function, if you had it set to "Play" then simply call your play 
function.  Make sense?

In terms of when you have to set the menu items -- a very long time ago 
I wrote the Menu Manager for the Mac II, and unless something drastic 
has changed under OSX, there's no way to change menu item names "on the 
fly", i.e. while a menu is down (not without writing your own 
MenuDefProc).  That means that you have to set the menu items before 
the menu goes down.   The right place to do this is in the menu's (or 
menubar's) mouseDown handler.  Make sure to "pass mouseDown" after 
you've set your menu items.
