Answer 1

what value is this statement?frame.getExtendedState() & ~frame.ICONIFIEDOne thing you can try is to ignore the mouse clicks using a GlassPane...
protected class GlassPane extends JPanel implements MouseListener, MouseMotionListener {
  public void mouseDragged(MouseEvent e) {}
  public void mouseMoved(MouseEvent e) {}
  public void mouseClicked(MouseEvent e) {}
  public void mouseEntered(MouseEvent e) {}
  public void mouseExited(MouseEvent e) {}
  public void mousePressed(MouseEvent e) {}
  public void mouseReleased(MouseEvent e) {}
// example of usage...
GlassPane glassPane = new GlassPane();
frame.setGlassPane(glassPane);
glassPane.setVisible(true);
