[Phenomenon]
Mouse freeze happens after clicking MB1 quickly and continuously.

[Step1] Compile PopupMenuButton.java, run PopupMenuButton.class
[Step2] A frame "AWTapp" with a button called "push me" appears.
[Step3] Click MB1 on "push me" button quickly and continuously.
[Step4] Mouse console will freeze, however hitting Esc-key can release the freeze.

//----PopupMenuButton.java-----
import java.awt.*;
import java.awt.event.*;

public class PopupMenuButton extends Button {
     static Class listener = MouseAdapter.class;

     PopupMenuButton(String label) {
super(label);
final PopupMenu popup = new PopupMenu();
popup.add(new MenuItem("item 1"));
popup.add(new MenuItem("item 2"));
popup.add(new MenuItem("item 3"));
add(popup);

          enableEvents(ActionEvent.MOUSE_EVENT_MASK);
addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
popup.show(PopupMenuButton.this, 0,
PopupMenuButton.this.getSize().height);
}
});
     }

     public static void main(String args[]) {
Frame frame = new Frame();
frame.setSize(100,100);
frame.add(new PopupMenuButton("push me"));
frame.setVisible(true);
     }
