hi, can anyone help me...

the background of my application is:

I have put 2 JMenuBar (say barA and barB) into the JFrame (say frameX).

Initially, in jbinit() of frameX, barA is set:
this.setJMenuBar(barA);

one menu item of barA invoke:
this.setJMenuBar(barB);
another menu item of barB invoke:
this.setJMenuBar(barA);

when I compiled and run the program, barA is shown on the frame
as expected.

However, when the first time I click that menu item to switch to barB,
the region showing the menu doesn't change.  It changes correctly only
if I resize the frame.

For the second and third time and so on.  The switching between barB and
barA are running very fine.  Only problem occurs at the first time to
switch the menu bar.

Any idea on which places I should take care to solve the problem?

thank you in advance.
