Actions that are bound to keyboard bindings via registerKeyboardAction or the
new InputMap/ActionMap functionality will not work(ie they won't get called) if
a mouse button is pressed. This works fine on NT using the 1.3fcs but on
Solaris, and HP for that matter, there appears to be a bug. This is important
because it is needed to support cancelling mouse based operations(like drawing)
via the Escape key.

The following test app will show the problem. Run it on NT and then on Solaris
and you'll notice the action will not fire on Solaris if you hold down a mouse
button.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class keytest extends JFrame {

   public static void main(String[] args) {
      new keytest();
   }
   public keytest() {
      addWindowListener(new WindowAdapter() {
         public void windowClosing(WindowEvent e) {
            System.exit(0);
         }}
      );

      final JPanel p = new JPanel();
      p.setOpaque(true);
      p.setBackground(Color.yellow);

      InputMap im = p.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW);
      im.put(KeyStroke.getKeyStroke("ESCAPE"), "esc");
      p.getActionMap().put("esc", new AbstractAction() {
         public void actionPerformed(ActionEvent e) {
            System.out.println("Action ESCAPE");
         }
      });

      getContentPane().add(p);
      pack();
      setBounds(300,300,300,300);
      setVisible(true);

      p.requestFocus();
      p.addKeyListener(new KeyAdapter() {
         public void keyPressed(KeyEvent e) {
            if (e.getKeyCode() == KeyEvent.VK_ESCAPE) {
               System.out.println("KeyListener ESCAPE");
            }
         }
      });
   }
}
