hi all,
here is the code i'm testing...

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class MnemonicTest extends JApplet {
        JMenu fileMenu;
        JMenu subMenu;
        JMenuItem window;
        JMenuItem exit;
        JButton button;
        public void init() {
                System.out.println("Init...");
                JMenuBar menuBar = new JMenuBar();
                setJMenuBar(menuBar);
                fileMenu = new JMenu("File");
                menuBar.add(fileMenu);
                subMenu = new JMenu("New");
                window= new JMenuItem("Window");
                window.setMnemonic('w');
                exit = new JMenuItem("Exit");
                exit.setMnemonic('x');
        
                subMenu.add(window);
                subMenu.setMnemonic('n');
                fileMenu.add(subMenu);
                fileMenu.add(exit);
                fileMenu.setMnemonic('f');
                fileMenu.setVisible(true);
                getContentPane().add(button = new JButton("press me"));
        }
}

i set all the mnemonics for the File menu in my applet so that i can invoke it from the keyboard but here is what happens,
1. when i do alt-f it popsup the File menu and by default it automatically selects the first item which is "New" menu in my applet. when i press alt-x it doesn't invoke the Exit option.
BUT
when instead of going via the keyboard, if i click on File by Mouse then i can select 'x' from the keyboard to invoke the Exit menu item.
please try it yourself and try to reproduce the error.
another issue i found is,
you see the button in my applet? if i don't put that button in my applet i can't invoke File menu via alt-f!!! I concluded that i had to put "something" in my applet area to make alt-f work so i did put a button. you can try removing the button and see what happens when you press alt-f.
i use IE5.0 , plugin-1.4.1_01.
here is the HTML i have,
