Fences Peek does not work.
The hotkey (win+space) works fine. On toggle my taskbar turns opaque, the current window loses focus, and slightly more shadow is applied to open windows. Unfortunately fences stay in the background.
As suggested in other threads, I tried a clean install, also excluding fences from windows security, with no success.
