Windows 10 upgraded from 7 and FSX was running well. Monitor Benq GW2765 at native 2560x1440. AMD Radeon HD 7800.
AMD Radeon updated the driver to 15.20.1062.1003 and now the programe is weird. However I set the window (Normal Window or Maximised) it starts in a full screen Window with toolbars etc. Alt-Enter either crashes to desktop with low res display or has a display about quarter of my screen way off to the left!
Everything else on the PC is running normally.
Any thoughts on what is going on here...
