========== to reproduce ========
- compile single source file included below
- run application:  java TipTest
- when app window appears, position another
  application (e.g. Win95 calculator) so that
  it is active, and partially obscures the 
  TipTest app window, like this:


   .....................
   |     TipTest       |
   |               .................
   |      *        |
   |               |   Calculator
   ................| (or other app)
                   |
                   .................  

- position the mouse (hover over but do
  NOT click) somewhere to the left of the
  calculator app. (approx. in area marked
  by the '*' character above).  At this
  point, the calculator app should STILL
  be the active window.

====== the bugs ================
BUG A
  as you rest the mouse cursor over
  the area shown above, the ToolTip will 
  appear, even though the TipTest 
  window/app is inactive.  This
  seems wrong.  The TipTest app/window 
  should NOT be processing mouse events
  (until the window is made active again).
  For an example of standard Windows behavior, 
  look at Netscape Communicator toolbar.  When
  another app is active in front of Communicator,
  Communicator's toolbar buttons ignore
  mouse "rollover" events.

BUG B
  Bug B happens because of Bug A.  With the
  mouse cursor resting over the area marked '*',
  wait for the ToolTip to display.  Then move the
  mouse slowly down toward the bottom edge of
  the frame, again WITHOUT any mouse clicks.
  When the mouse cursor crosses the frame's
  bottom edge, the TipTest app/window is 
  repainted and brought to the FRONT of the 
  Calculator app, as though TipTest had been 
  made active.  However, it is not active, as
  the colors of the two applications title bars
  remain as they were.  Also, any keystrokes are
  processed by the calculator program.

        f.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
        f.getContentPane().add(p);
        f.setSize(new Dimension(350,250));
        f.setVisible(true);
    }

    public String getToolTipText(MouseEvent e)
    {
        return "( x="+e.getX()+",y="+e.getY()+")";
    }
