Dizzie, Page 19 contains the following: "After installation, you will need to securely register/authorize your copy of Poser 5. You must contact Curious Labs either by telephone, email, or via secure Web connection in order to complete the process. You will be prompted to register your copy of Poser 5 when you launch it." I asked a CL representative if this meant I would need a new code if changes to my hardware or OS were made. I was advised "in most cases, no." Of course, the corollary is "in some cases, yes." Perhaps CL has done me a favour by instituting copy protection. It has forced me to start using Wings3D and the copy of Carrara 2 I recently purchased. (Wings3D for modeling, Carrara for staging, texturing and rendering.) Frankly, I find the idea of knowing that a piece is completely by own, without reliance upon other peoples' creativity, both exhilarating and liberating. - Jack
