Is your figure a group of objects with the bone set applied to the group? If it is, you might want to make sure the group is closed in the sequencer tray when you move the bones.(the bone group needs to be open to get to specific bones but not the group that is being deformed). This happend to me before and I reported it. Seemed like they said that it was fixed in the patch, but I am on a PC so who knows. mdc guam usa
