java.awt.Frame.setResizable(false) does not prevent the user from resizing the frame

Steps to reproduce:
Compile and run the attached code
Press <UnSet Resizable>
<Click + Drag> any corner of the window

import java.awt.*;

public class FrameTest extends AppFrame
{
    final String RESIZABLE = "Set Resizable";
    final String NOTRESIZABLE = "UnSet Resizable";
    Label label;

    public static void main(String args[])
    {
       FrameTest f = new FrameTest();
       f.show();       
    }

    public FrameTest()
    {
       super("Frame Test");
       Panel panel = new Panel();

       add("North", panel);
       panel.add( new Button(RESIZABLE) );
       panel.add( new Button(NOTRESIZABLE) );
       panel.add( label = new Label( new Boolean( isResizable() ).toString() ) );
       resize(200, 200);       
    }

    public boolean action(Event evt, Object obj)
    {
       if (evt.target instanceof Button)
       {
          String lbl = (String) obj;
          if ( lbl.equals(RESIZABLE) )
             setResizable(true);
          else if ( lbl.equals(NOTRESIZABLE) )
             setResizable(false);
          else
             return false;

          label.setText( new Boolean( isResizable() ).toString() );
          return true;

       }
       return super.action(evt, obj);
    }
}

Synopsis: setResizable(false) still lets you maximize a frame

2. Run the program
3. Double-click the header or press the maximize button.
4. The window is maximized with the contents in the upper left corner.

hi,

    Currently Frames do not have methods to enable and disable minimize and maximize buttons. 
Only way out is to disable events to these buttons. Better method would be to have functions 
which allow the prograammer to enable or disable these buttons.

Dipanshu.
