Your using JDK 1.2 or higher, right?
Change resize to setSize - resize was deprecated as of 1.1. Don't use action(Event, Object) - it was deprecated as of 1.1, too. To activate the close button, use addActionListener (see below). Add another action listener for your Show menu.
Button close = new Button("close");
// Add this code.
close.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
// Your code to handle the event.
dialog.hide();
dialog.dispose();
// End of new code.
dialog.add(close);
