Set the main form's ShowWindow property to 2 (As Top-Level Form)

For all other forms that are called from this one, set their ShowWindow property to 1 (In Top-Level Form)

Each form that has a ShowWindow setting of 1 will become children of the top-level form (whichever form has a ShowWindow setting of 2) and won't be able to be moved outside of it.

If no form has the setting of 2, then the "child" forms are placed within the _screen.
