        Description


        This bug occurs with JDK1.1.5J, JDK1.1.5FCS, JDK1.1.6L, JDK1.1.6M and
        JDK1.1.6N.
         
        From JDK1.1.5J onwardsn, appletviewer crashes when you try
        to click on a menu of an inactive frame.

        In JDK1.1.4J, appletviewer does not crash, but the inactive frame just
        gains the focus, and the menu items aren't displayed.
         
        Test Case:
         
        b518877.java:
        import java.applet.*;
        import java.awt.*;
        import java.awt.event.*;
        public class b518877
               extends Applet
        {
            private Frame _mFrame1;
            private Frame _mFrame2;
         
            public b518877()
            {
            }
         
            public void start()
            {
                _mFrame1 = new TestFrame("Frame 1");
                _mFrame2 = new TestFrame("Frame 2");
         
                _mFrame1.setBounds(100, 100, 300, 200);
                _mFrame2.setBounds(125, 125, 300, 200);

        b518877.html:
        <applet code="b518877" width=400 height=400>
        </applet>
         
         
        To reproduce the bug:

        1. Start the appletviewer
        2. Move "Frame 2" around a little bit so that you can see the menus of the
        inactive frame "Frame 1"
        3. Click on any menu of "Frame 1"
        4. appletviewer will crash
         
        A Dr. Watson for Windows NT message box will be generated:
        Exception: access violation(0xc0000005), Address: 0x0000001

        (The hex address for Address will vary from installation to installation)
