Applet repainting error in IE 5.5 using the scrollbars

Question

I've created a real straight forward applet using swing components to test out this error. It consists of a couple of JButtons & JLabels added to a JPanel that's the JPanel is added to the ContentPane. I'm using the Java Plug-in 1.3 on a Windows 2000 box using IE 5.5. When I view my applet everything is just fine. But when I'm using the browser scrollbars to view the rest of my applet and try to scroll down, the applet controls and everything within the applet does not get repainted properly onto the screen. Everything in the applet gets painted on top of their old controls a couple of pixels off making it impossible to use. When I scroll to the bottom and top of the page the applet repaints just fine, but it's when I'm scrolling in the middle of the page is where the applet can not repaint properly. I have tested this in Netscape 6.0 and everything works just fine. I'mnot sure what could be causing this but maybe one of you have cameacross this problem before and could help out.
thanks,
Peter Landis.

Here's the code:
import java.awt.*;
import javax.swing.*;
public class TestRepaint extends JApplet
public void init()
     Container contentPane = getContentPane();
     JPanel panel = new JPanel();
panel.setBackground(Color.lightGray);
controls(panel);
     // Grid
     contentPane.add(panel);
public void controls(JPanel p)
JLabel imagelabel = new JLabel();
JLabel imagelabel2 = new JLabel();
// Create some labels
JLabel label_1 = new JLabel("TEST 1");
JLabel label_2 = new JLabel("TEST 2");
JLabel label_3 = new JLabel("TEST 3");
JLabel label_4 = new JLabel("TEST 4");
JLabel label_5 = new JLabel("TEST 5");
JLabel label_6 = new JLabel("TEST 6");
JLabel label_7 = new JLabel("TEST 7");
setLabelControl(label_1);
setLabelControl(label_2);
setLabelControl(label_3);
setLabelControl(label_4);
setLabelControl(label_5);
setLabelControl(label_6);
setLabelControl(label_7);
// Buttons
JButton b1 = new JButton("Button 1");
JButton b2 = new JButton("Button 2");
JButton b3 = new JButton("Button 3");
JButton b4 = new JButton("Button 4");
JButton b5 = new JButton("Button 5");
JButton b6 = new JButton("Button 6");
JButton b7 = new JButton("Button 7");
setButtonControl(b1);
setButtonControl(b2);
setButtonControl(b3);
setButtonControl(b4);
setButtonControl(b5);
setButtonControl(b6);
setButtonControl(b7);
// Layout
     GridBagLayout gridbag = new GridBagLayout();
     GridBagConstraints c = new GridBagConstraints();
p.setLayout(gridbag);
c.anchor = GridBagConstraints.WEST;
     c.fill = GridBagConstraints.BOTH;
c.weightx = 1.0;
c.gridwidth = 1;
// Note Inset is (Top, Left, Bottom, Right);
c.insets = new Insets(0,5,20,0);
     p.add(label_3,c);
     c.insets = new Insets(0,5,20,1);
p.add(b3,c);
c.insets = new Insets(0,5,20,0);
     p.add(label_4,c);
c.gridwidth = GridBagConstraints.REMAINDER;
     c.insets = new Insets(0,5,20,1);
p.add(b4,c);
c.gridwidth = 1;
c.insets = new Insets(0,5,20,0);
     p.add(label_5,c);
     c.insets = new Insets(0,5,20,1);
p.add(b5,c);
c.insets = new Insets(0,5,20,0);
     p.add(label_6,c);
c.gridwidth = GridBagConstraints.REMAINDER;
     c.insets = new Insets(0,5,20,1);
p.add(b6,c);
public void setButtonControl(JButton button)
          button.setBackground(Color.white);
void setLabelControl(JLabel l)
          l.setFont(new Font("Helvetica", Font.BOLD, 14) );
l.setForeground(Color.black);
