Should I use the module or external version of SquawkBox?
If you are going to be running SquawkBox on one computer and Flight Simulator on another, you will need to use the external version of SquawkBox. If you are running everything on one computer you have the choice between the two. If it’s important to you to have everything in one application and for the SquawkBox window to always be accessible, run the module version. This will typically be the case if you have a single monitor and you run Flight Simulator in full screen or maximized mode. If you have multiple monitors you may find it advantageous to run the external version of SquawkBox and position the SquawkBox window on your secondary monitor.
