I upgraded from Fences 3 to Fences 4 yesterday, and now I can't seem to move any icons from one fence to another, or even to a new position within a fence.  I can drag icons and the move, but as soon as I drop them in a new location, they go right back to where they were.

I assume I'm missing some new setting, but I looked and can't find anything that would seem to cause this behavior.  I tried unlocking the feces, but just like with Fences 3, that only allows me to move and resize my fences (which I don't want to do).  The icons are still stuck where they were.

What am I missing?

I'm using Fences 4.0.0.3 in Windows 10 Pro (x64), build 19044.1645
