Hello,
Sorry to hear you are having issues. No it can't be done. Fences, as mentioned and discussed lot of time in this forum before, is a desktop level application. It can't not simply appear on top of any open Windows. Do not confused Fences with Docks. Currently, what you can do is use the hotkeys to make Fences "appear" on top of a Windows. Refer here for recent discussion on this same request: https://forums.stardock.com/538934
Thank you
