Help!

I have V 4.2 in PoserPro 2010.  Sometimes when I have applied morphs, conforming figures, and parented props, V4's neck, right middle and pinky fingers, and left middle and pinky fingers will stop working.  Bend, twist, and side to side do not work, nor do the morphform Grasp options in either right or left hand.

I don't know if this is a figure or program issue, but I have the most recent V4 update (as far as I know) and PoserPro SR1.

Any help would be appreciated.  Thanks.
