"The new features being add-ons to the basic Poser 4 codes is not a surmise..." The reason that I stated it was a "surmise" is that I do not have P5 and could not verify it personally. We seem to have some programmers within the community that could, possibly, check the code to see if there is a substantial amount of the base code that exists within both P4 and P5. The reappearance of P4 bugs strongly suggests, if not proves, this to be true without proper investigation.
