When Docky is not in autohide mode, every d'n'd action on the bottom third of the screen will fail, probably because the window manager (?) thinks that I'm dropping in the docky window (which occupies a huge part of the screen, as is evident by switching to metacity w/o compositing).
This means that one cannot reorganize icons on the bottom part of the desktop, but also d'n'd to any window placed on the bottom part of the screen won't work!
Steps to reproduce: just try to drag and drop something to any window in the lower part of your screen.
Do version: 7.96 from do-testers
Window manager: Compiz and Metacity
Distribution: Ubuntu Intrepid
Maybe it's possible to make Docky's window as large as the actual bar, and eventually enlarge the window geometry only when the icon zoom effect is performed or Do is summoned?
