Cheers Tony, that worked, and I have to say it felt like my viewport was supercharged while playing around with it.  Back then, Poser figures felt slightly laggy like the current ones do today, but a low-poly figure like that is a piece of cake for a modern graphics card to handle - the fluidity is very nice!

She still has to rank as the ugliest Poser figure I've ever seen, though. I've never seen anything like it.  Loading her into the viewport and seeing her only confirmed it, I thought to myself, bloody hell!
