When I drag the centers, It updates the Center values in the joint editor window, but then everything goes back to zero if I dare to touch something else (for example the fall off zones). Typing in the boxes does sweet FA! they just reset to zero as soon as I change the focus to something else. I keep thinking I've got some kind of bug, but then I've thought that so many times nd usually it's just because I'm not following the rigid preocedures Metacreations thought up, and then didn't bother to include pop warning messages for when you abuse them.
