Ok I have definitly determined my problems are some kind of issue with openGL and my video card (only with Poser). It is an intermitent issue because sometimes it works and sometimes it doesn't. When in Sreed mode it never happens. Like others I thought it was V4 that was causing it but it's just intermittent and almost any character  will cause it eventually. I'm starting to think that displaying transperency may be the issue. I will do some more tests.
