I had placed three controls on a UserControl and had them all perfectly
docked together filling up the UserControl.

I needed to add a fourth controls docked to the top.  So I dropped it on the
UserControl, changed the new control to Dock = top and changed the taborder
of all the other controls (bumped each up by 1) .  But when I start changing
the other controls back to dock = left, fill, etc... they expand the entire
height of the form making the top controls appear to overlap all the other
controls .  In a sense, the controls "slip" under the new 4th control.

If I were to remove them all and place new controls from scratch they all
appear fine and respect the control with the "Top" boundary - then it works
fine. But I would have to redo alot of settings if I took this route!!!

How can I make sure that any newly added controls dock appropriately with
the previous controls

Thanks
