Quote - Are you trying to reset the hot point on an object with bones? It won't work in that case.

No the object in question is an automobile, and I'm just trying to change the pivot point, I've done it before in Carrara 6 Pro and now all of a sudden it doesn't work any more, again it works fine in Carrara 5 Pro. I am using Vista 64 on a Dell XPS Quad and unfortunately I can't put XP 64 on this computer XP is much better at handling files than Vista 64.
