Sb5 : UI : minor : Dropping into root from the pasteboard

When dropping a selection of text into the root level of the Binder, opting to drop in as a new root level item, not a sub-item of an existing binder object – the little black guide that shows you where it will be dropped remains visible after the drop, and will remain visible until another dragging action is initiated. This only happens at the root level as far as I can tell.

D’oh! Easy one - fixed for beta 6/1.0.
