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.
When using the middle mouse button on a remote desktop windowed screen, to open a new tab in firefox on the remote system, causes the window to move to opposite screen.
