I am not sure this has anything to do with Display Fusion. I have windows 10x64. I fly simulators..when I load up the simulator and I have it up on say say screen 1..I have 5 connected lol..anyway when I move mouse to another screen. It puts the first screen in pause (if that makes sense) and screen two becomes active. What I am trying to do is use the app on screen two (say a sound equalizer to filter sound on screen1 which is the simulator screen) to filter out noise. I can't because its either screen 1 or 2 and not both?

Maybe I lost you and could be something to do in windows.

I have really enjoyed Display Fusion for a number of years.
