                       I made a target null for a hand, I wanted
to use IK to have the character move its arm so that the hand went to the
face.
When I started moving the target null not only the hand and arm moved, but the
whole body pivoted.

Bruce,

    I haven't spent a lot of time with IK hierarchies, but I believe your
problem arises from using a "target null". I'm not sure how this would affect
things, but I wouldn't do it this way. If you need to have any of your objects
(body parts) have complex rotations, parent the object to a null rotating on
the second set of axes you desire. Then parent the null object to the next
object up the IK chain.

I hope this works,
