Button not Displaying in JRE 1.4.2

Question

We have one Applet with Image button and it used to work fine with JRE 1.4.1. If I install JRE 1.4.2 in my Machine Image Buttons are not displaying.
We coded as follows
public class ImageButton extends JButton {
private Image image = null ;
private ActionListener listener = null ;
public ImageButton( Image image ) {
super(new ImageIcon ( image ));
this.image = image ;
setCursor(new Cursor ( Cursor.HAND_CURSOR ) ) ;
setBorderPainted ( false ) ;
setOpaque(false) ;
setBorder(null);
setMargin(new Insets ( 0, 0, 0, 0 ) ) ;
public class StartPanel extends OutputPanel implements ActionListener {
private ImageButton pb_START = new ImageButton ( AppletUtil.loadImage ( "start.gif" ) ) ;
private RadarApplet applet = null ;
/** A panel to hold buttons */
private JPanel pnl_BUTTONS = new JPanel () ;
* Constructor for StartPanel.
public StartPanel( RadarApplet applet ) {
super();
this.applet = applet ;
setBackground ( Color.white ) ;
pnl_BUTTONS.setLayout ( new FlowLayout( FlowLayout.CENTER, 3, 0 ) ) ;
pnl_BUTTONS.setBackground ( Color.white ) ;
pnl_BUTTONS.add ( pb_START ) ;
add ( pnl_BUTTONS ) ;
pb_START.addActionListener ( this ) ;
showProgress(false) ;
setLowerComponent ( pnl_BUTTONS ) ;
setText( RadarConfiguration.getString( "ready_to_download" ) ) ;
setDescription( RadarConfiguration.getString( "ready_to_download_desc" ) ) ;
* @see java.awt.event.ActionListener#actionPerformed(ActionEvent)
public void actionPerformed(ActionEvent e) {
( e.getSource() == pb_START )
new Thread ( new Runnable () {
public void run () {
applet.startProcess() ;
} ).start() ;
}

Answer 1

One thing to add for clarification, the problem I described is the application display problem and NOT the screen capture problem.
