No, it seems to be a Poser bug. I create figures with PHI files and the "Convert Hier File" menu. When I load the new figure and open Joint Editor, my Poser usually crashes (Poser 4 on a Mac). My work around: Load the new figure, and save the library again (you can replace the existing one). "Convert Hier File" and "Create New Figure" (in Hierarchy Editor) create a .cr2 version 3.0. Poser crashes, when you edit joints. "Add to Library" in the library palette creates a .cr2 version 4.01, which works with the Joint Editor.
