Sorry, it does.

When you have a container that arranges its children, its arrangement is 
applied when the form is saved.

The children control are sorted in a way depending on the arrangement. 
For exemple, for a vertical arrangement, controls are sorted by their Y 
property. It's done so that the result is similar to how you layout the 
children controls in the form editor.

This order is the z-order of the children controls. So, if you use the 
Raise() and Lower() method on these children, it will arrange them again.

Note that you can see the control order in the Hierarchy tab of the form 
editor.

Please post your full project if you want me to look at it.
