First, it doesn't work that the fences switching between desktop pages but the icon moved between the desktop pages, and I try to find program's bugs in my computer that made Fence can't work usually , but nothing to find. Then, I change the Fence setting about 'view' of the icon, from Medium to Classic or Large, finally the Fences can be switched between desktop pages whatever using right/left of mouse or using keyboard.
It's really bothering! It costs for my some moths. Hope for the next Fence X.X not find it .
