If you were to do a little bit of research you'd find that it is in fact a problem in Poser that has been known for a long time already, but you may not have encountered it if you have never used figures that utilize scaling to change body proportions. Many of those who have used Apollo Maximus for instance are well aware of this issue.

I don't know how well DAZ has informed their customers about this issue, perhaps they could have been more in-your-face about it.
