@Scott: the problem you mention is not a DockManager issue. That is a Docky issue. Please feel free to file a bug about that against the 'docky' project on launchpad. Please check to ensure this bug has not already been reported there. Note that it might be listed more general but should probably mention a freeze when closing preferences.
The fact the Skype helper triggers it is just coincidental (I think).
