        Description

        This bug only happens on Windows 95 and Windows NT.

        This bug can be reproduced in the following scenario:
        - select a menu from the menubar
        - select a menu item and don't move the mouse
        - the menu item handler sets the busy cursor, does some processing, then reset
          the cursor back to the default cursor.
        - you will see that the busy cursor stays until the user moves the mouse.
