It's strange. It depends on the scene. I made a scene with two balls in it and have no problems loading a frame out of the middle. The scene I had problems with still loads with frame 0 all the time. I have loaded the scene in Poser 6 and saved it again to see if something changes. It did not help at all.

Certain scenes will load, others won't. Not very helpfull.
