When I installed Windows 10, FSX (Steam Edition) would run properly, but only in Windowed mode. When I try to run the program full screen (which is best for my laptop), it works until you try something which requires another window to appear (such as view the flight plan or view the map). When you do this, the screen goes black and nothing appears - though you can get back to the flight screen using Esc.
I suspect this is something to do with the Desktop Windows Manager in Windows 10. In Windows 8.1 the application works fine and seems to allow MSX to take control of the windows, but in Windows 10 MSX can't do this.
Because of this problem and a few other issues with (non-critical) apps on my Lenovo G500 laptop, I decided to go back to Windows 8.1, which is working fine.
I think Windows 10 looks good in most areas, but until I'm satisfied that MSX and my laptop will work properly with Windows 10, I'm going to stick with Windows 8.1.
