Hi.
It is so hot in South Korea.
My name is Sung-eun Yang. Glad to meet you.

* I have found a problem, using Graphics's method, seem to be a bug.

Following simple example code is proposed to be act below.
 1. At the beginning of its run, nothing will be painted in the Frame.
 2. Once you press a mouse button inside the Frame, a red filled Box would appear.

  import java.awt.*;
  import java.awt.event.*;
  public class Test extends Component {
   public Test() {
     enableEvents(AWTEvent.MOUSE_EVENT_MASK);
   }
   public void processMouseEvent(MouseEvent e) {
     if (e.getID() == MouseEvent.MOUSE_PRESSED) {
       System.out.println("mouse pressed");
       Graphics g = getGraphics();
       g.setColor(Color.red);
       g.fillRect(10,10,50,50);
     }
   }
   public static void main(String[] args) {
     Frame f = new Frame();
     f.add(new Test());
     f.setLocation(300,450);
     f.setSize(200,150);
     f.setVisible(true);
   }
  }

* Problem is: *
 The drawing methods of Graphics -fillRect()... - didn't any effective work(anything)
    on it's first call involved by first mouse pressing.
 but, on it's second call, these methods did work properly.

 Mouse event was properly delivered, thus I think that the methods of Graphics
 contain bug...

*[java -version]
  java version "1.2.1"
  Classic VM (build JDK-1.2.1-A, native threads)

* windows NT 4 (Service pack 3)

Please, reply to me.
Have a nice day.
Thanks.
