invoking the desired pattern. This will make that new Modal Form
"invisible" from tools like UISpy. When manually closed, and then
manually Invoked (from the same thread) the Modal Form will be
present as a child of the parent form. That might complicate and
annoy while developing your automation. The discovery of controls or
elements within the child Modal Form should be as normal by the
FindFirst() and FindAll() methods. Just FYI. */
