Modeless dialogs

Question

Hi,
I am developing under Windows XP, SP2, all updates installed. When I run the program below, the modeless dialog disappears after a few seconds when I click into the parent frame. Obviously the frame repaints and ignores the dialog. But the dialog is still in front of the frame. If you click somewhere in the frame, where the dialog had been shown, the title bar of the dialog reappears. This happens under JRE 1.6.0_03.
If I run under JRE 1.5.0_14, the dialog stays in front visibly, but the frame is also repainted after a click (focus change). This can be noticed because the screen flickers.
Does somebody have a workaround for JRE 1.6.0_3?
Thank you
Jochen
Here the code:
package divtest;
import java.awt.Color;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.Point;
import javax.swing.JDialog;
import javax.swing.JFrame;
public class ModelessDialogTest extends JFrame {
  public ModelessDialogTest() {
    super("ModelessDialogTest Frame");
    setSize(800, 600);
    setVisible(true);
    Container contentPane = getContentPane();
    contentPane.setBackground(Color.red);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    JDialog md = new JDialog(this, "ModelessDialog", false);
    md.getContentPane().setBackground(Color.yellow);
    md.setSize(200,150);
          Dimension parentSize = getSize();
          Dimension mdSize = md.getSize();
          Point parentLoc = getLocation();
          parentLoc.x += (parentSize.width - mdSize.width) / 2;
          parentLoc.y += (parentSize.height - mdSize.height) / 3;
          md.setLocation(parentLoc);
    md.setVisible(true);
  public static void main(String args[]) {
    ModelessDialogTest mdt = new ModelessDialogTest();
}

Found a solution myself.
I used
System.Windows.Forms.Application.Run(new MyForm());
instead of
Form frm = new MyForm();
frm.Show();
