I've just bought Fences as I'd played with the demo version and thought it would help keep my desktop the way I want it.  Wrong!  Who thought it was a good idea NOT to be able to switch OFF auto-arrange within the Fence?  That person needs sacking!  This is a huge mistake!  I was under the impression that Fences allowed us to arrange the desktop the way we want, not the Microsoft way!
And while you're fixing that I'd also like to suggest another improvement.  Being able to drag a title-less Fence by clicking and dragging within the Fence.  I don't really want title-bars, I know what I've got in the Fence!
