OOPS I found out if you use the mouse to shorten the size of the rolled up fence, then you may position
it anywhere. The downside of this is you do not see all the icons at once. You must use the scroll bar
on the fence (generated when you shorten the fence) to scroll up or down to see all the icons.
So DaveBax is correct that you can position it anywhere, just a matter if you want to see all the icons
at once, or use the scroll bar.
