It could be that the Fences are locked. Try right clicking on an empty area of the desktop and then do the following.

Once that has been done, see if you can use the controls on the fence or move or resize it.

If this does not help, make sure you have the latest version of Fences installed. The latest installer can be accessed when you sign into your account here: https://store.stardock.com/myaccount/products
