The secret is to have the figure(s) expanded in the animation pallette. The latest Poser Pro 2014 patch seems to have caused Poser's default behavior to collapse all figures upon loading them into the scene, so you'll have to click the little arrow for each figure after they are added.

I'm actually glad they did this, as I had previously though that Poser was only ever capable of cycling parts for the first figure in the scene. That being said, @thinkcooper, if you're listening, it should be an option that one can change in preferences, so if one desires, figures can load fully expanded every time.

@Miss Nancy: this seems to be a Windows-specific Poser issue. Thanks for helping to clarify that :)
