EVALUATION
One can easily reproduce this bug by launching SwingSet2, choosing JOptionPane demo and then clicking "Show Message Dialog" button. Now, click on the "SwingSet2" window title bar and you'll see the window rapidly gaining and loosing focus. The reason it happens is because we don't prevent modally blocked NSWindows from becoming main/key.
