      Description

      Java application window hides under all of other windows(native or java)
      due to mouseEntered event.


         >>Following instruction and code demonstrates the problem.
         >>
         >>1.Run the java program and place the window on the another window.
         >> e:\test java TestW
         >> +---------+
         >> |TestW | X
         >> +-| |----------------+
         >> | | Y | Window B |
         >> | +---------+ |
         >>
         >>2.Set the mouse focus to the desk top window by pressing the mouse left
         >> button there.
         >>3.Move the mouse cursor from the desk top window to the test program
         >> window, i.e., from the position X to Y in the figure above. Do not
         >> move mouse cursor into the black box area in the TestW window because
         >> it will cause exception. I'll report this in another submission
         >> as it seems to be different bug.
         >>4.The TestW window is automatically hidden under another window, i.e.,
         >> Window B in the figure above.
