Okay, I think I found the Trigger. For me, it only occurs if I have an unsaved File (one with no File Name). If anyone finds this is not the case for them, please contact e-frontier Tech Support.

I will also add that it does it for me in all versions of Poser when the File has not been saved yet or is not an existing File. (I had a hard time duplicating because I always open Poser by a File I am working on.)
