Here's the thing though lkenndal. Yes, Daz updated D/S to handle V4.2. How much did you pay for that? For that matter how did you pay for the V4.2 update for Daz Studio or Poser?

As far as the supposed "idiosyncratic" problems. I would like you to explain the way you are using the term. All character/figures or models have mannerism or habit inside a program. So what. Daz characters worked to my satisfaction in most of those versions even when they were fundamentally different in the way they worked and behaved(BUGS and all). By the way they still sell most of them and never update them to use newer content either. 

It doesn't bother me you want to stick with Poser, but it seems people make up and imagine reasons for Daz supporting Poser because deep down they know if Daz doesn't support Poser then Poser is probably screwed. Idiosyncratic really.
