I have a menu, the WHENSELECTEDFN of which calls SHADEITEM to gray out the selected item.'
One of the "spots" in the menu is blank': it''s a 2 x 4 menu with 7 entries.  A funny thing happens when I select the "empty" item':  the very first item in the menu changes to "NIL", but changes back when I select it.'
'
...'
'
the body of the WHENSELECTEDFN':'
(LAMBDA (ITEM MENU KEY) (SHADEITEM ITEM MENU 0))'
