I have a menubar that contains a certain menu. This menu has several menuitems.
One of these menuitems has the same mnemonic as the menu itself.
When I press Alt-(this same mnemonic), normally it must open the menu so I can
choose the menuitem myself. But unfortunatly, it sends directly the action related to the menuitem having this mnemonic, without opening the menu. Which is completely incoherent.

The problem is seen in Java 1.2.2-005, but not in Java 1.3.0-C where is works
correctly

Test case:

I sent you a example that shows the problem.
After launching the example, see the menuitems in the menubar.
Then try to type Alt-F, it opens directly a JOptionPane telling that the FROM
menuitem has been fired. Normally, it must open then File menu without firing anything.
