It is "said" that P2012 corrected the inherent problems previous versions of Poser had with PMD files. And I haven't experienced the issues that others have had with EBMs.

Which leads me to believe that corruption might be associated with a mixture of OS, unique installation peculiarities on different PC systems... or God pats Ashley on the head for living a blameless and pure life up to date.

While the later is demonstrably a rediculous joke, the gremilns at play between each and every Poser installation in conjunction with the uniqueness of everone's PC set-up could explain the difference between my experience and that of others. The flutterby effect.
