Actually, if you are subclassing ImageWindow anyway, you can just

        @Override
        public void windowClosing(WindowEvent e) {
                return; // prevent it from closing
        }

If you cannot do that, a quick and dirty way is to set the member variable
"closed" to true. It is dirty because you have to use reflection; this
member variable is protected.
