I have the same problem that "denully" !
I have try the solution of Zubaz ... and that is working when I drag the Fences to the right.
But it is impossible to drag the Fences to the left.
I have searched a solution and I have found that the problem is my toolbar that is at LEFT not in BOTTOM.
So, to organize my Fences, I must first put my toolbar in BOTTOM, then move the Fences to left or right and then put my toolbar at LEFT.
This is not very userfriendly !
For me, this is a bug
Have Stardock a solution to this problem ?
Thank to advise me !
