Discussion
By default, selecting or deselecting a menu item from a pop-up menu changes its state. Selecting a menu item from a pull-down menu does not automatically alter the state of the item. To disassociate the current selection from the state of menu items, set the altersStateOfSelectedItem property to false.
Subclassers can override this method to catch all select calls.
