java version "1.3beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3beta-O)
Java(TM) HotSpot Client VM (build 1.3beta-O, mixed mode)

Steps to reproduce:

1. Compile and run the source code below under Windows.
   You should see a single frame with a button and a menu bar. The button
   should have the keyboard focus.
2. Click on "Menu" in the menu bar. There should be one menu item, currently
   selected.
3. Hit return to select that menu item. Instead, a message will be printed
   to standard out saying that the button had been pressed, and that the
   menu item was not activated.

I tested this using JDK 1.3beta, but not RC1 (yet). I also tested it using
the Metal L&F; the problem doesn't seem to manifest in it. Only the Windows
L&F seems to have the problem. (I haven't tested Motif.)
