I've started trying to get the hang of IK in poser.  I like it, but often switch back and forth.  I don't have any trouble when I do this with legs, but I've noticed arms seem to have all kinds of trouble.  Often I'll go back after working later in the animation to previous key frames and see that the hands/arms are contorted and folded up, no where close to where I had them posed.  Applying a saved pose doesn't seem to help unless I urn IK back on.  Does anyone have a guess as to what I'm doing wrong here?  I'm setting key frames intentionally, but unless I remember to save the pose at each of them the damage is done and I have to repose.
