Anything, it doesn't matter. That is, in regard to characters I've worked with a lot. A fresh V4 or M4 work fine. My guess is that somewhere in the process of changing props or hair I am hitting keys that are changing the angle of the camera (effectively, the stage). After working in Silo or Blender, I have caught myself trying to change the angles with the Alt or Shift keys in Poser. Ctrl+Z works great if I notice it in time, but eventually my regular characters get messed up this way and I don't know how to fix it. Don't know how much it effects the overall positioning of the garments, but after watching a fresh Victoria spin around into a dance pose with a dress all nicely flared out I have to wonder.
