When I start the game the resolution is set to 1366x768.
But the screen is not in full screen mode.
When I change the resolution to 1920x1080 the game is in full screen.
But I can't play the game in 1920x1080 because of my graphic card (gt740m).
So I must play the game in 1366x768.
When I installed the game a week ago and I played the game in 1366x768 the game was in full screen mode.
But now when I started the game I have this problem.
