I've written a short program to workaround the modal dialog from modal dialog bug
but I've discovered another bug.

When a frame from a frame is opened and the parent frame is disabled and enabled very often,
the program crashes java.exe or locks.
Here is a short program. Compile it and click on the windows as fast as you can for a few minutes.
Sometimes it doesn't crash if it doesn't, restart the program and repeat the clicking as fast as possible.
After 2 or three restarts the program must be crashed the first time.
Sometimes it doesn't crash sometimes it simply locks the system.

 


import java.awt.*;

class bug3 extends Frame {
    Frame parent;

    bug3 (Frame parent) {
        super();
        setLayout(new BorderLayout());
        add("North", new Button("Test"));
        resize(200,200);
        move(0,0);
        this.parent = parent;
        parent.disable();
    }
    public boolean handleEvent(Event ev) {
        if(ev.id == Event.MOUSE_DOWN) {
            parent.enable();
            this.dispose();
            return true;
        }
        return super.handleEvent(ev);
        }



}




class bug2 extends Frame {

    bug2() {
        super();
        resize(200,200);
        move(0,0);
    }


    public boolean handleEvent(Event ev) {
        if(ev.id == Event.MOUSE_DOWN) {
            (new bug3(this)).show();
            return true;
        }
        return super.handleEvent(ev);
        }


    public static void main(String [] args) {
        (new bug2()).show();

    }
}
