[Pharo-project] Category Renaming under Monticello

Hi, When I rename a category, Monticello does not seem to pick up the necessary (class definition) changes, even when I manually accept each class definition. I was hoping to use category renaming to move some classes out of an MC package and into a seperate new one. I also wanted to rename a category, but that would give the same issue I guess. I am sure this is worth a FAQ entry, but I could find anything. Anyone any idea ? Thx, Sven
