Let's get this straight. You can start Poser 6, add figures and props to the scene, they show up in the preview window, and you can render. "But if I open any other things." What things? If you try File->Open->[anything other than a .pz3], no wonder that Poser doesn't work. You can import them, not open them. Or do you mean opening a window? You can't open the Parameters palette or the Grouping tool? That might be a Python related problem - many Poser windows rely on Pyton/Tkinter. I know there was a problem with some Python libraries in the initial Poser 6 release, one of the libraries was outdated and had to be replaced by the correct version from python.org. I haven't checked whether SR1 fixes that bug.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
