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'm guessing your program forces a virtual key-press to get programs to minimize/maximize..
KMplayer uses the hotkey '5' to enter fullscreen, instead of the default win(Up).
It would be awesome if you could create a custom function to force a keypress.. as that is far more powerful, and makes it easier to get around non-standard keymaps...
With the new Scripted Functions in 7.0, you can create a Function to send keystrokes to the app, and then call that from a Window Location rule. Please let me know if you'd like some help creating the scripted function
