The Tk problem showed up in Poser Pro first. Follow the link to see if its the same problem you were having. The linked post has the error message in it. If that's your error message, do the column=0 fix.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
