For some reason, when I try to save Props with animated poses it has never worked.  However, it is most likely moot, as in the P4 scene, the sword has no real inherent motion of it's own as it is parented to the right hand, and moves with the hand.  I will probably try to keyframe the sword next, and see if that has any effect...but the flames losing their motion as well is really disturbing me, as they are loaded with keyframes to get them to spread down the blade, and flicker (hense all the waves and magnets).  I did spend some time setting this up when I was using the Poser 4 Pro Pack and really do not want to have to go through that ll again.  I decided to ask in these forums as the help I received from Tech support was no help at all (they essentially told me to recreate the scene from the ground up in poser 7).
