Fullscreen mode problems

[devunion]

Hello all, I've tried to create simple fullscreen app in Java. And I have some problems with it. Take a look at dialog which need to be displayed above the form. Try to drag it. (I've tested on JDK 5 and 6) Does it possible to fix such problems at all?

import javax.swing.*;
import java.awt.*;

public class Fullscreen {

    public static void main(String[] args) throws Exception {
        System.out.println("Probando Full Screen...");
        JFrame fr = new JFrame();
        fr.setTitle("Test Title");
        fr.getContentPane().add(new JLabel("Test content"));
        fr.setResizable(false);
//        fr.setPreferredSize(new Dimension(1024, 768));
//        fr.pack();

        if (!fr.isDisplayable()) {
            fr.setUndecorated(true);
        }
        GraphicsDevice gd = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
        gd.setFullScreenWindow(fr);
        fr.setVisible(true);

        MyDialog dlg = new MyDialog(fr);
        dlg.setLocationRelativeTo(fr);
        dlg.setVisible(true);


        Thread.sleep(10000);
        System.exit(0);
    }

    static class MyDialog extends JDialog {
        MyDialog(Frame frame) throws HeadlessException {
            super(frame, "Parent dialog", false);

            initComponents();
            setPreferredSize(new Dimension(640, 480));
            pack();
        }

        private void initComponents() {
            JPanel panel = new JPanel(new FlowLayout(0, 0, FlowLayout.CENTER));

            JButton jButton = new JButton("Show dialog");

            panel.add(jButton);

            getContentPane().setLayout(new BorderLayout());
            getContentPane().add(panel, BorderLayout.NORTH);
        }
    }
}

Thanks.

instead of
GraphicsDevice gd = GraphicsEnvironment.getLocalGraphicsEnvironment(). getDefaultScreenDevice();
gd.setFullScreenWindow(fr);

try
fr.setSize(Toolkit.getDefaultToolkit().getScreenSi ze());
