Needing a sphinx for an illustration I decided to use Nerd's Catrina figure (available here in Freestuff).  I remember working with this figure when I first downloaded it years ago and it didn't have any problems.   However, now when I try to bring it in Poser 6 or 7 I get the results you can see in the image.  Something very weird is going on with the arm joints where the P4woman's blend with the animal's.   I tried zeroing joints and re-applying the poses Nerd supplies but I still have the same problem. 

Has anyone experienced something like this?  Is there a workaround for P6 or 7? 
Installing P4 is not an option as there are other items I'll also be using that cannot be used in P4 correctly.
