This issue is also present in the Virtual Desktops application. When you have it try to change the wallpaper of the virtual desktop, it also conflicts with Fences.
Just my .02 - since no one ever reads these posts, I'm betting that this issue will continue until someone gets mad enough to contact Stardock Support. (yes mad, not angry - you have to be mad to contact Stardock Support) I mean what are they supposed to say, "Thank you for contacting us. Your question/issue/concern will be handled in the order in which it was received. Estimated wait queue is 2 years. Thank you for using Stardock Software, and have a great day. Click."
I really love Stardock Software, but they have gotten so big, they seem to forget about what made them great in the first place. Sorry, this post wasn't meant to be a rant, but I have been slowly going crazy over the lack of response. As soon as I started to post, it just sort of came out. Again - forgive my madness.
