Hello KarenJ and pjz99,

Thanks for your replies. I have all of the V4 files in an external runtime so both Poser 7 and Poser 8 are accessing the same files. I have in fact run the installers (several times actually to make sure that I didn't miss anything) but to no effect. It is odd that the S4 head morphs install and work for both Poser versions, but the body morphs only install and work work in Poser 8. Strangely, if I save an S4 based figure in Poser 8 and then open it in Poser 7 all of the morphs work. But they will not work on an S4 base figure opened directly in Poser 7.
