[Qt-interest] Qt Designer action drag and drop to menubar and toolbar not working on OS X?

[Mitchell L Model]

It seems to me that Qt Designer's drag and drop from the action editor  
to a main window's menubar or toolbar isn't working. I drag, but  
nothing happens -- when I'm over a menu that already has some entries,  
it doesn't drop down, and I can't get anything onto the toolbar. [Qt  
4.6, Mac OS 10.5].
