Screen doesn't clear between looping images

Question

Problem with an applet. It automatically loops through images that are loaded from a separate file called Pic. The images have been drawn as graphics objects, so aren't images like gifs. But repaint doesn't clear the previous graphic object, so they load on top of each other. If I manually refresh, the previous graphic does disappear. Can anyone help?? The code is:
<pre>
import java.awt.*;
import java.awt.event.*;
import java.util.Random;
import javax.swing.*;
/* <APPLET CODE="Stage3.class" HEIGHT=300 WIDTH=300></APPLET> */
public class Stage3 extends JApplet implements ActionListener {
Pic pic1 = new Pic();
int current = 0;
Timer timer;
boolean frozen = false;
public void init() {
setBackground(Color.white);
int delay = 2000;
timer = new Timer(delay, this);
timer.setInitialDelay(0);
timer.setCoalesce(true);
pic1.rollValue(9);
//Invoked by the browser only. invokeLater not needed
//because startAnimation can be called from any thread.
public void start() {
startAnimation();
//Can be invoked from any thread.
public synchronized void startAnimation() {
if (frozen) { }
else {
//Start animating!
if (!timer.isRunning()) {
timer.start();
public void paint( Graphics g ) {
g.setColor(this.getBackground());
pic1.drawPic(g, 5, 50);
public void actionPerformed(ActionEvent e) {
pic1.rollValue(9);
repaint();
</pre>

Answer 1

I find calling validate(); invalidate(); works for me but I never tried it in an applet.
