How to prevent a ZSphere from rotating while oyu move it

[MikeHart]

ZB2 has a little feature that I find anoying right now. Try something like this. Create a parent ZSphere. Then turn on X-Symmertrie(???). Then place 2 child ZSpheres, one on each isde of the parent ZS. Now, when you move the child ZSs, they rotate. Why is that? When you do a preview <A> of the skinning, you can see that this causes the surfaces to rotate to. The more the ZSs rotate, the more ugly is the result.

Any clue on how to avoid the rotating???

I'm at work now so I can't post a screenshot to explain the problem visually.
