If I understand properly, I think I have seen this effect with P5 SR4, as well. I have some scripts which set up characters by loading figures and components and assembling them in Poser. Simple stuff, but some of them had problems. Files with certain names (Numerical names and names which closely resembled a folder name in a file path found elsewhere in the same script seemed to be the problems) simply would not open with Python. Python would apparently try to find them, then give up and move on. A script which encountered this problem, once it finished running, would print "The file was not found. Do you want to continue looking for files?" in the console window - twice. It seems to me that it must have been answering its own question and doing pretty much what you've outlined above. Or is that a separate issue?

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.
