This change was made because some ORM tools (some of the rowset stuff I think) pulled the scale and stored it off regardless of whether it was used or not. The storing code did "validation" that required it be >= 0. So everyone using these frameworks was screwed whether they needed the scale or not. So we changed it to keep them happy at the expense of people like used based on a size of the camps measurement alone. Kris Jurka
