Hi there. I'm trying to get this simple test program working, which pops up
a menu, when you press the windows key (if you don't have the windows key,
then change the keyReleased check to a different keycode say, VK_A) in the
textfield. The problem is I get an Exception thrown, and key navigation does
not work at all. Is this just buggy swing? Any workarounds?
thanks very much for your help.
