I am wondering if the geometry itself could have anything in it that is causing your problem. I think you can define an axis of rotation and maybe the center point, but this sounds like a Poser problem. What on Earth could be in the geometry that would limit movement in Poser? The point being, I wonder if remaking the prop will have any effect? I am guesing the problem is down stream from this. If you just import the prop, does it move OK? If it does, see if Mike is locked or something. Mike may be where the hangup is.
