Gradebook

It might be handy to add such a case at:
http://docs.moodle.org/en/experimental:_gb_tutoring
or at least describe in the talk page the issue and the resolution....
Personally, I would thin it a bug if a catgory apparently removed from grade computation via the gui was none the less being included, and I think it wo9uld be great if Gary or someone could explain the intent behind the fuinctionality if this is not a bug....
