Hi,
I have a problem when BS3 starts, it's fullscreen, but the game is rotated by 90 degrees (as in attached image).
I tried o change resolution of my screen, game resolution and other stuff, but without resolving it.
This is an issue happened to me with other games and usually i just alt+tab and the game switch automatically in windowed mode and become oriented in the right wa, but not this time.
I'm playing with a win10 tabletPC.
Thanks for your help

I'm not familiar with Windows tablets, but I suppose you could try installing DxWnd to force the game to run in windowed mode.
