You might want to ask about it in the Python forum. I sometimes have Python problems, but usually re-initializing Python fixes it. Sometimes I get an error message when I try to re-initialize Python, and I have to re-start Poser to get it working again. I think it's a memory issue. Maybe my hard drive's getting too full or something. Or maybe it's just Poser weirdness. It tends to get corrupt every once in awhile, and you have to reinstall.
