Bookmark is how someone gets updates to the thread in their email. People do this on interesting threads so they can get to the answer. As for your answer, I am not too sure, but if the problem came from Python, and continues after a restart of Poser, here are a few ideas. 1) Go to File-->Reinitialize Python. Sometimes Python just needs that in Poser. 2) Restart the computer, and start a new file. This one may be wrecked. 3) You may want to go ahead and reinstall Poser. Maybe something is corrupted internally. If this is the same file that is doing the same thing, make sure you try a brand new Poser file. As I said, this one may be totally corrupted. (It happens, save early, save often, is my mantra.) Hope some of this helps!
