Motif tear-off menus cannot be closed after you have completed the tear-off steps. For example, the problem occurs when you perform the following steps:
Choose the File menu from the CDE Calendar Manager.
Choose the dotted line at the top of the menu.
The File menu is re-created as an independent dialog box that contains buttons for each menu item.
Using the window manager menu to close the tear-off menu does not work. If you minimize the application, the tear-off menu is also iconified but does not completely close. The menu closes only if you exit the application.
Workaround: Do not use tear-off menus.
