The following application attempts to create a Popup menu.

It works as expected on Solaris.
On Windows NT, the menu doesn't popup when the right button is
pressed.

import java.awt.event.*;

class PopupMenuBug extends Frame {

    PopupMenu pm;
    MenuItem pmi;
    PopupMenuTrigger pmt;

    public PopupMenuBug() {
        setLayout(new BorderLayout());
        pm = new PopupMenu();
pmi = new MenuItem("I'm a MenuItem in a PopupMenu");
        pm.add(pmi);

        pmt = new PopupMenuTrigger(pm);
add("South", pmt);

    pmi.addActionListener(new MyActionListener());

pack();
show();
    }

    public static void main(String[] args) {
        new PopupMenuBug();
    }
}

      FontMetrics fm = g.getFontMetrics();
      int w = fm.stringWidth("Right Click Here");
