So, on both my laptop and my desktop, Fullscreen and Windowed Fullscreen are the same thing. So I asked the Guru's on Twitter what the intended difference was and may have come across a bug in the game. Grant Rodiek @SimGuruGrant 10m @IonaShepard You can minimize the program in windowed full screen. On my laptop, my desktop, and a friend's desktop, there is no minimize in Windowed Fullscreen. I'd like to know if it works, or doesn't work, for anyone here?
