Wow!..thanks for the info. That Poser is not good in Vista. I do have my copy of windows Vista, but not installed yet. Will install in the end of the year or better yet, will work on a new system. Now that I have my copy, that I will not have to go out and spend huge dollars later on. But this is great heads up on the situation. I really do not know if EF will work on patches (fixes, updates) for us poser users.
