Exception unter Win NT 3.51 after dispose a Frame.

Name: mc57594 Date: 02/21/97


Hi all,

May be is that a Feature or a WinNT3.5 Bug,
because there is no problem on WinNT4.0.

The simple programm opens a Frame window which
contains a button.

When we click on this button, a second frame with a button
appears.

When we click on this last button, this frame is hidden
with hide() and disposed with dispose().

Then the exception comes (at once or after few times).

I didn't see anything about this problem in known-bug-list,
I would like to know if that's a Windows bug,
a Virtual-machine bug or a failer in my programm.

Thanks for all,

Philippe.

Here is the code.
#
# TestSubWnd.java
#
import java.awt.*;

public class TestSubWnd extends Frame
{
        String message;
        Button myBt;
        TextArea myText;

        public TestSubWnd (String title)
        {
                super (title);
                myBt = new Button ("Button...");
                add("South", myBt);
        }
        public boolean handleEvent (Event e)
        {
                if (e.id == e.ACTION_EVENT)
                {
                        NewWnd wnd = new NewWnd (this, "Test Standart Window");
                        return true;
                }
                return super.handleEvent(e);
        }

        public static void main (String args[])
        {
                TestSubWnd f = new TestSubWnd("Test von Subwindow");
                f.pack();
                f.show();
        }
}

                                {
