Well I'm not sure what happened for sure. I was just playing
around with a piece of code I had made. You click start and then
the ball is supposed to start. When you click stop the ball should stop.
It worked fine but then I repleaced the ball with a rectangle and then it
gave me an error and told me to contact you at this URL.
Here is a copy of my code if you need to further inspect it.
I dont't really care either way as all I was doing was playing around
and have absolutley NO need of a moving square, if you know
what I mean!! =) So here is my code:

import java.awt.*; //Importing the necessary classes.
import java.awt.event.*;
import java.applet.Applet;

public class roundup2 extends Applet implements Runnable
{ //My main class.
 String one = "Start!";
 String two = "Stop"; //Declaring strings, ints
 boolean isMoving; //and booleans.
 int x1=0,y1=0;
 int vpos = 0;
 Image offScreenImage; //My image and graphics variable.
 Graphics offScreenGraphics;
 Font f=new Font("SansSerif",Font.BOLD,32); //Set my font.
 FontMetrics fm = getFontMetrics(f);
 Thread runner;
 int textWidth = fm.stringWidth(one); //Declaring more ints.
 int textHeight = fm.getHeight();
 int textWidth1 = fm.stringWidth(two);
 int textHeight1 = fm.getHeight();
 
  public void init() //Init method.
  {
   offScreenImage = createImage (getSize().width, getSize().height);
   offScreenGraphics = offScreenImage.getGraphics();
   addMouseListener(new MouseAdapter() //Mouse Listener which gets
    { //the mouse clicks at the positions
     public void mouseClicked(MouseEvent e) //defined in this method.
     {
      x1=e.getX();
      y1=e.getY();
      if((x1<10+textWidth)&&(y1<10+textHeight)&&(y1>textHeight-10)&&(!isMoving))
      {
       isMoving = true; //Checking if the click is over the
       start(); //Start button.
      }
       else if((x1<10+textWidth1)&&(y1<110+textHeight1)&&(y1>125)&&(isMoving))
       {
       isMoving = false; //Checking if the click is over
       } //the Stop button.
     }
    });
   }
 
 public void start() //My start method which starts the
 { //applet.
   runner = null;
   if (runner == null)
  {
   runner = new Thread(this);
   runner.start();
  }
 }
 
 public void stop() //The stop method which stops the
 { //applet if it is moved to the
  if (runner!=null) //background and the like.
  {
   runner.stop();
   runner = null;
  }
 }
 
 public void update (Graphics g) //The update method which is
 { //'supposed' to take the flicker out.
  paint(g); //Mind you I said 'supposed' to. =)
 }
 
 public void run() //The run method which makes the
 { //applet run.
  while(isMoving)
  {
   vpos +=1; //The vpos of the ball is
   if (vpos==getSize().height) //increased by one.
    { //If the ball exits the bottom of
     vpos=0-70; //the screen then it should be
    } //repainted at the top.
     repaint();
     try
     {
      Thread.sleep (10); //The ball should wait 5 somethings
     } //before continuing.
      catch (InterruptedException e) {}
  } //Catching exceptions.
 }
   
 public void paint(Graphics g) //My paint method which paints all
 { //the images to the screen.
  offScreenGraphics.setColor (getBackground());
  offScreenGraphics.fillRect (0,0,getSize().width, getSize().height);
  offScreenGraphics.setColor (Color.blue);
  offScreenGraphics.drawRect(275,vpos,70,70);
  offScreenGraphics.setFont(f);
  offScreenGraphics.setColor (Color.green);
  offScreenGraphics.drawString(one,10,50); //I'm setting colors and drawing
  offScreenGraphics.setColor (Color.red); //strings on my board.
  offScreenGraphics.drawString(two,10,150);
  g.drawImage (offScreenImage,0,0,this);
 }
} //With this parentheses I end this
//beautiful program.

(from subsequent report 84287:)

Hello again! I just submiited a bug, but when I ran the program again it worked and never gave me a hassle!
So I'll report the error it gave me in DOS when I tried to run it

A nonfatal internal JIT (3.00.039(x)) error 'IsSimpleMethod: Undefined JAVA opcode(bf)'
has occured in: 'sun/applet/AppletPanel.getNextEvent ()Lsun/applet/AppletEvent;': Interpreting method.
Then it told me to report it to you so I did. Thanx for your time.

Sincerely, Joey Mauro(JAVA hopeful)
