Applet Button acting weirdly...

Question

Hello
I'm quite new at Java, and new to this forum, so don't be too hard;)
I've got a problem with a awt.button in an Applet. When i click on the button it seems to send two events, and thus executing twice the code. I would like it to execute only once the code.
I've tried changing the MouseListener from MouseClicked to MouseReleased, but doesn't seem to change anything. I've also tried to put a button.setEnabled(false) in the code executed, but still doesn't change anything.
This is weird to me, because i've also got an application version of the program and it doesn't have that problem.
Could you please help me...

public class ScanAPPlet extends Applet {
  JButton jButStart = new JButton();
jButStart.addMouseListener(new ScanAPPlet_jButStart_mouseAdapter(this));
  void jButStart_mouseReleased(MouseEvent e) {
    String param = (String) jCCommand.getSelectedItem();
    Prog programme = new Prog(this, param);
    thread = new Thread(programme);
    thread.start();
class ScanAPPlet_jButStop_mouseAdapter extends java.awt.event.MouseAdapter {
  ScanAPPlet adaptee;
  ScanAPPlet_jButStop_mouseAdapter(ScanAPPlet adaptee) {
    this.adaptee = adaptee;
  public void mouseClicked(MouseEvent e) {
    adaptee.jButStop_mouseClicked(e);
}

Ok thanks for everything, i think i've found the problem!
For reference, it's a problem of Jbuilder, it changed the constructor of the Applet like this:
public ScanAPPlet() {
    try {
      Init();
    catch (Exception e) {
      e.printStackTrace();
  }and then launches the applet with :
public static void main(String[] args) {
   ScanAPPlet applet = new ScanAPPlet();
   applet.isStandalone = true;
   Frame frame;
   frame = new Frame();
   frame.setTitle("Cadre de l'applet");
   frame.add(applet, BorderLayout.CENTER);
   applet.init();
   applet.start();
   frame.setSize(600,300);
   Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
   frame.setLocation((d.width - frame.getSize().width) / 2, (d.height - frame.getSize().height) / 2);
   frame.setVisible(true);
}So in the end, there's the init() has been called twice. Probably making the problem. I deleted the changed constructor and it seems to be working.
But Thanks of lot for your help!!
