A JInternalFrame is not activated by mouse clicks in its
interior.
 This happens if the glass pane (or the root pane
and hence
the glass pane too) of the internal frame has
been replaced.

Repeat by:

o compile T01.java

o run it

o the program creates a Desktop with size 400x400.
  Inside the desktop there are two internal frames,
  Frame1 and Frame2

o move the frames so that they overlap a little; it should be
  possible to see which frame is in the foreground, and it should
  be possible to click in them both.

o click in Frame2 to bring it to the foreground

o click in the FextField in Frame1

---> Frame2 is still showing as being activated, Frame1 does not
  come to the foreground. But it is possible to enter data
  in the TextField of frame1

Reason:
In jdk1.2.2 BasicInternalFrameUI the glassPaneDispatcher is
attached to the glass pane permanently. When the Frame is
deactivated, the glasspane becomes visible, the listener
catches clicks and activates the frame. When the
Frame is activated, the glasspane is made invisible.
But when the RootPane or the GlassPane is replaced, the listener
stays attached to the old glasspane.
In jdk1.2 the glassPaneDispatcher was installed/uninstalled
when the frame was deactivated/activated.

 * the frame is not activated by mouse clicks.
