JWindow Full Screen

Question

I created a splash screen with a JWindow so that the user can't close it while it's being displayed. Here is my code:
     GraphicsEnvironment ge = GraphicsEnvironment.
        getLocalGraphicsEnvironment();
        GraphicsDevice gs = ge.getDefaultScreenDevice();
     JPanel panel = (JPanel)window.getContentPane();
     panel.setBorder(BorderFactory.createBevelBorder(BevelBorder.RAISED));
     panel.setBackground(Color.black);
     if (show)
          JProgressBar progressBar = new JProgressBar(JProgressBar.HORIZONTAL);
          progressBar.setIndeterminate(true);
          progressBar.setForeground(Color.blue);
          panel.setLayout(new BorderLayout());
          panel.add(new JLabel(new ImageIcon("marstotal.gif")), BorderLayout.NORTH);
          panel.add(progressBar, BorderLayout.SOUTH);
          gs.setFullScreenWindow(window);
          window.pack();
          window.show();
          mainMenu();
     }My code works full screen in Windows XP, but does not work in Linux or Windows 98,ME, or 2000. Anyone know how to fix this? OR how I can restructure my code so that it will work on all operating systems?

Thanx guys. I finally got my window (although now it's an undecorated JFrame) to get focus. Well, kinda. It says it has focus. However, whenever I press a key, it doesn't fire a KeyEvent. My class implements a KeyListener interface. I defined all the methods (obviously, otherwise it wouldn't compile). In each of the KeyListener methods, I put System.out.println ("Whatever method reached."). It doesn't print anything out, although the window has focus and I'm pressing like a thousand buttons.
