Beginners Question MDI

I may be just too stupid but can't figure this out:

I created a MDI app with child docs. Only the MDI main form uses CommandBars and Docking Control.

When I create a pane, it is docked to the mainapp covering the entire right side up to the title bar.

I'd like it to be almost this way except I want the docking panel to stay in the client area and not go all the way up to the title bar. Did I express this right?

To be more precise:

when I use VB's own menus, things are ok. As soon as I use codejock menu bars, they move around when I for example dock a panel at the top side. I want to use codejock menus and I want them to stay where they are when the user docks things around...

Any suggestions greatly appreciated...
