I added a new menu (with menu items) to the menubar ("&Report"). Pressing
Alt-R will activate/highlight the menu but it does not expand downward to
show the menu items like the standard menus (and like other custom menus I've
produced in the past with the same code). There are no other menus that
start with "&R".

Any ideas as to why this won't automatically drop down (expand) when I press
Atl-R?
