Whenever I try to save something to the Libraries in PP12, I get a "Warning: cannot open " followed by the path of the file I'm trying to create.  Also, I can't save anything directly into my Runtime from Poser File Editor either.  When I do, it doesn't appear in the refreshed Libraries.  I have to save it to my Desktop and then copy it in.  I suspect it has something to do with Vista's ever-annoying security hang-ups, but I've tried editing file permissions to no avail.  Is anyone else having similar problems and, better yet, any possible remedies?

Thanks in advance!
