I can hit Windows+P and turn off my other monitors but that throws about 10 windows into my main moirot to be placed back later. Annoying at best.

yeah I'm having this problem too. It only allows me to play the game on my monitor on the left and changing which monitor is the main one doesn't fix the issue. Hopefully there's a patch which fixes this :)

I have 2 monitors. My main monitor is monitor 1, it's also where I launch the game and it's launcher from. Still the game opens fullscreen in monitor 2. There's no way to drag it and no options for which monitor to open it in. Anyone got any ideas about this?

Anyone having issues with dual monitors?
