How to force application windows back to main screen

When using an external monitor with your laptop sometimes windows remembers you left a form on the external monitor after you have broken down your setup and gone elsewhere without said external monitor.  This can be frustrating because later when a form pops up and is in limbo off the LCD monitor of your laptop all work stops until you can recover your run away form.

This is one method that has partially worked for me:

- Use Alt+Tab to put the focus on the invisible frame.

- Press Alt+Space on the keyboard.

- Press M on the keyboard.

- Use the left/right/up/down arrow keys until you can see the invisible frame.
