What are you trying to do? I think you need to have a rethink about how your UI is going to look as you seem to be adding an Internal Frame to a Frame, with the menus on the Internal Frame, and on the Frame as well...

Also, Internal Frames can't be Modal (unless you do some proper hacking -- none of which works 100% believe me I've tried)...
