I've also run into that problem but not with a textfield, it was when use
the arrows to go through a JList

I think that it comes not from JMenuBar, but the component in which you type
some keys !

In fact, you try to enter some keys in your textfield, the keyEvent is
passed through all listeners of keyEvents,
and as it is your frame which has the focus, the keyEvents are delivered at
the end to the JMenuBar.

You must give explicitely the focus at your textfield, your frame must lose
the focus when your enter
the textfield and perhaps you have to add you own Keylistener !

Hope it could give you some hints, :)Anne
