Select the Charactures body, Not the head, or any other body part. Then in your parameters under Morphforms. you will see head size. dial it back to "0". That should do it. If I am happy with that charactures head size, I will delete Head size from Morphforms, then you the head size won't happen to that characture again. or just leave it in, that shouldn't happen again on that figure. But that can happen when you start a figure and start adding morphs to a new figure. So if that happens, you know how to correct it.
