The alpha did this right. The game would start on my primary monitor, and fullscreen on my primary monitor.

But the beta starts on monitor 1 (The monitor connected on port 1 on the graphics card), and also fullscreens on monitor 1, meaning I can only play it fullscreen on my little 1360x768 TV.

I can only run the game in regular windowed mode if I want it on my primary monitor. Both fullscreen and fullscreen windowed puts it on monitor 1.

As a work-around, I've had to make a small program that removes the window border from the windowed option, and places it onto my primary monitor.
