<BR>Notice that if popup menu is owned by a menubar, you must associate first the menubar
|
||
|
|
to its toplevel. In this case, when you create a menu popup, its clone window is also
|
||
|
|
created, and DynamicHelp::register detects the exitence of the clone window and maps
|
||
|
|
events to it.
