Mess with MouseEvents on Lightweight components

On following example MyButton doesn't get first MOUSE_PRESSED after
MOUSE_MOVED and gets MOUSE_ENTERED/MOUSE_EXITED on every press or
release of mouse button.

import java.awt.*;
import java.awt.event.*;

public class MouseTest extends Frame {
    public static void main(String argv[]) {
MouseTest test = new MouseTest();
test.setVisible(true);
    }

    MouseTest() {
super("MouseTest");
Container c = new LWContainer();
Component b = new MyButton();
c.add(b);
add(c);
setSize(200,200);
    }
}

class LWContainer extends Container implements MouseMotionListener {
    LWContainer() {
addMouseMotionListener(this);
    }

    public void mouseMoved(MouseEvent e) {
System.out.println("Mouse Moved");
    }

    public void mouseDragged(MouseEvent e) {
System.out.println("Mouse Dragged");
    }
}

class MyButton extends Component implements MouseListener {
    MyButton() {
setSize(50,30);
setBackground(Color.red);
addMouseListener(this);
    }
    
    public void paint(Graphics g) {
Dimension d = getSize();
g.clearRect(0, 0, d.width - 1, d.height -1);
    }

    public void mousePressed(MouseEvent me) {
System.out.println("Mouse Pressed");
    }
    
    public void mouseReleased(MouseEvent me) {
System.out.println("Mouse Released");
    }

    public void mouseExited(MouseEvent me) {
System.out.println("Mouse Exited");
    }

    public void mouseEntered(MouseEvent me) {
System.out.println("Mouse Entered");
    }

    public void mouseClicked(MouseEvent me) {
System.out.println("Mouse Clicked");
    }
}
