Desktop Manager Problem

Question

Hello everyone,
im using a JDesktopPane to manage around 18 InternalFrames.
Because of that amount i need a way to acces everyone of them in a click.
I created a menu to acces everyone of them.
I started everyone as iconified.
BUT
When i restore with the menu (that uses the desktopmanager)they somehow go crazy and the up right corner buttons get changed (i lost the iconify one)
AND
As soon as i use the DesktopManager to iconify them they stop listening to the mouse
Whats wrong?
