Where have you tested it - any OS 8/9? I can't speak for OS-X but I have been unable to get it working for exactly the same reasons that I discovered earlier. I once wasted 4 weeks trying to get Dan's scripts to run on Mac before I finally gave up. It fails for two reasons: - It won't run anything using Tkinter, and that means it won't run anything with a user interface - Poser itself ignores some of its own commands, like hiding dials In other words - it just sucks, period, dot. I have tried every PPP version that has been officially available, including all SR1-3 patches, each in every combination with every OS8-9 version that I keep - and it just fails, fails, fails. Even if one Tkinter call occasionally works (unlikely enough, but sometimes it attempts to give you some false hope :-) you can be sure that it won't run a second time - even after a "restart Python" marathon subsequent uses will crash PPP. The only workaround is to quit Poser for every single script run. Now that's what they call "Pro" these days, eh!? Since I fell from grace with Poser's company some time ago (and can't try the beta versions any longer), there is (sadly) nothing I can offer, other than this: If you plan to buy the Mac PPP mainly for Python scripts, you might as well set your banknotes on fire.
