Here's the scenario:
I have two forms to display on the screen: Form1 and Form2. The Form2 is
displayed after the user clicks a button on Form1 (which is already
displayed). Form2 is automatically displayed in front of Form1. Both forms
are loaded modeless (you can't load a second form if the first is modal).

Here's the problem:
I need the capacity to change the ZOrder of the two forms without unloading
either of them. That is I need to programmatically force Form1 to be in front
of Form2, or alternatively Form2 in front of Form1.

I have not been able to find a way to do this. The forms themselves to not
have a ZOrder property. The only other way I can think of is via an API
though I'm not sure which API function would solve this.

Any ideas?
