I've just made available an update: build 385428 contains a different way to render fullscreen that positively fixes the "forced screen resolution change" issue (switching the screen to 1024*768 at game start forcedly) As long as it was present only on limited machines, please let me know if there is any other similar issue. I will soon introduce another update to switch forth and back the old and new system to maximise flexibility. thanks for your patience and enjoy!
