Mouse released event for scrollbar

Question

Hello,
I have a java.awt.Scrollbar component on applet.
I need to perform actions when user releases the mouse from the
scrollbar. For example the user presses the mouse on the scrollbars
tracking rectangle and starts to track. Then the values of the
scrollbar changes and finally user releases the mouse left button-
this final event (mouse release) is in my interest. How can i get
mouse release event from scrollbar? The AdjustmentListener does not
suit for me because it fires AdjustmentEvents even then when the user
hasn't released the mouse. I need to perform more actions for every
scrollbar's change; so my applet i slow at the moment, because every
"tracking in scrollbar" creates a lot of events before the mouse is
finally released.
I added a MouseListener for my scrollbar, but mouseReleased event does
not work. Can yo help me?
Thank you, any help would be nice.
Here is some demo code i tried:
import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
public class Kerimisriba1 extends Applet implements
AdjustmentListener, MouseListener{
     Scrollbar kerimisriba=new Scrollbar(Scrollbar.VERTICAL, 20, 5, 1,
100); //algv��rtus, nupu suurus, v�him ja suurim v��rtus
     TextField tf=new TextField(10);
     public Kerimisriba1(){
          setLayout(new BorderLayout());
          add(kerimisriba, BorderLayout.WEST);
          add(tf, BorderLayout.SOUTH);
          //kerimisriba.addAdjustmentListener(this);
          kerimisriba.addMouseListener(this);
          System.out.println("AdjustmentEvent.TRACK="+AdjustmentEvent.TRACK);
     public void adjustmentValueChanged(AdjustmentEvent e){
          //System.out.println(e.getAdjustmentType());
          // tf.setText(kerimisriba.getValue()+"");
     public void mouseReleased(MouseEvent me){
          tf.setText("mouseReleased");
     public void mouseClicked(MouseEvent me){}      
     public void mouseEntered(MouseEvent me){}
     public void mouseExited(MouseEvent me){}
     public void mousePressed(MouseEvent me){}
}

I made a screenshot of how the applet works in my computer:

As you see in the java console,
the statement System.out.println("mouseReleased");
does not executes,
in my computer.
I tried this on co-workers comuter with Internet Explorer- there was no mouse release event either.
I hope i'm not very annoying, but i still need help:)
I replaced the constructor with init() method:
import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
public class Kerimisriba1 extends Applet implements AdjustmentListener, MouseListener{
     Scrollbar kerimisriba=new Scrollbar(Scrollbar.VERTICAL, 20, 5, 1, 100); //algv��rtus, nupu suurus, v�him ja suurim v��rtus
     TextField tf=new TextField(10);
     public void init(){
          kerimisriba.addAdjustmentListener(this);
          setLayout(new BorderLayout());
          kerimisriba.addMouseListener(this);
          add(kerimisriba, BorderLayout.WEST);
          add(tf, BorderLayout.SOUTH);          
          System.out.println("AdjustmentEvent.TRACK="+AdjustmentEvent.TRACK);
     public void adjustmentValueChanged(AdjustmentEvent e){
          System.out.println(e.getAdjustmentType());
          tf.setText(kerimisriba.getValue()+"");
     public void mouseReleased(MouseEvent me){
          tf.setText("mouseReleased");
          System.out.println("mouseReleased");
     public void mouseClicked(MouseEvent me){
          System.out.println("mouseClicked");
     public void mouseEntered(MouseEvent me){}
     public void mouseExited(MouseEvent me){}
     public void mousePressed(MouseEvent me){
          System.out.println("mousePressed");
