	Bug: stuck menu items are being cleared.
		A partial fix is in, but the event target causes the menu to be cleared
		when the mouse moves off the label.
		
		Current status is that the label is cleared when moving from the menu container
		to a menu item that has a sub menu.
	
	
	Menu items contain these attributes:
		mrid = menu id
		srid = sub menu id
		irid = item index
		
		Note the mrid and srid are ids, and irid is an index.
