If a toolkit supports "tear-off" menus, the menu can remain on screen for an extended period, so the status of the individual menu items can change while the menu is displayed. Relying upon an on-popup callback is likely to result in tear-off menus not working properly. -- Glynn Clements <[email protected]>
