This may sound odd, but I can't figure out what is causing my game to swap monitors during game play, but it seems to only happen while I have DisplayFusion running. So I usually close DF, but that's annoying because I have to reopen it afterwards.

It seems to be a combination of two buttons, with one likely being as I hold the mouse scroll button down and then pressing another mouse or even keyboard button. It's aggravating because I can't figure out what combination causes it, and it's usually when I'm in a heated battle, and I'm frantically clicking, swapping weapons,etc., then bam, the game swaps to the other monitor.

Looking through DF, I didn't see any monitor-swapping shortcuts that jumped out at me. Can anyone confirm if or what shortcuts there are for swapping monitors so I can narrow down the culprit?

Thank you!

Yes, that's where I was looking though didn't think any of those were the culprit. I went ahead and disabled them for now. Fingers crossed!
