@Miss Nancy:

It looks like all three errors are due to path handling.  The script is expecting to have received a path pointing to the .vwt location, but has received a NoneType object.  Am I correct in the understanding that you are running this on a Mac?

Hmm.  If Poser is crashing when you try to use or delete the new morph dials, presumably something isn't finalized before you try that.  See if saving the .pz3, closing Poser, then re-opening the saved file helps at all with the crash error.  Was there any sort of error message associated with the applcation crashes?

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
