Hello, I have a problem that is making me mad.
I have an application with a menubar that lets me change the JPanel to
show.
This panels are using gridBagLayout to localize and resize their
graphical  components.
When I have five created panels to show all is rigth. If the number of
panels is greater (so number of graphical components grow) and I use
the menubar to see one of my panels, the layout redistribute the
components without sense.
It resizes the components , localizes them with greater y positions
....

I have tryed with another layout manager (BorderLayout and FlowLayout)
but the result is the same.
I have tryed to set preferred , minimum and maximum size attributes of
components but the result is the same.
...
Is there no way to lock a layout?

Is there anyone with the same problem? Please I need some clue.
Thanks in advanced.
