Moshi, I get the same result as I showed in reply 5.
I dragged the calculator app off the Start10 start menu, and I get a blank icon that is labeled "app" and it does not launch.
that's either a Fences or a Start10 (or both) bug then.
it's probably Start10, but if you'd try to drag and drop from Start10 to an Explorer Windows and that would work, then Fences is to blame.
i use neither ( i think the Windows 10 start menu is the best ever), so Windows works as intended here.
