If you downloaded DisplayFusion 12.0 and are having issues with languages please re-download and re-install. We have repacked the release as 12.0c with the languages fixed.
I currently use Display fusions to manage my triple monitor gaming setup. The problem is when I alt tab from a FULL SCREEn windowed game and then go back to it, the windows taskbar does not dissapear and it stays in place all the time. I cant do anything about it. This didn't happen on Win 7 so I am assuming its a Win 10 issue.
