"CL lied" probably refers to the fact that in some of the discussion between the release of Poser 4 and Poser 5 (significant time) representatives of Curious Labs said (are thought to have said) the program was being rewritten from the ground up. You can explore the perspectives on this by searching through the archives here and at the other Poser forums. Please note: I am not taking a position, only trying to relate relevant information.
