Thank you Thomas, I did not know of this function. Then it is possible to run on one computer and connect it to two displays and have the same functions as I have now.
But since my wife want to have her PC now and then, I will stay with the current configuration.
Windows 10-64, FSX Acc, Acer Aspire xc600 3.00 GHz, 12 GB RAM, AMD Radeon HD 7000, Saitek FLY5 joystick, TacPack v 1.4.2.6
