popups appearing where 2nd monitor would be but not connected to 2nd monitor

Hi

I normally work with 2 screens and I have gone away on business so I just have my laptop. I am using MBC software and when I click on menus that launch a pop up, like Group&collapse, preview, add scenario it is opening it up but I cannot access it as it is where my 2nd monitor would normally be. I then have to force shut down the software as I cannot continue.

I've gone through all the screen settings and tried google.

Any thoughts.
