Hi, All of a sudden, for no reason that I can understand, my copy of Poser 4 PP has got sick. When I run the program, any model in the window is invisible - but it's there, as I can see the outlines of body sections if I run my mouse over the pic. And if I press render, Poser starts using the CPU at 100%, but sits there forever with no results. I'm not sure what I might have done to cause this. I installed a few new models, but nothing out of the ordinary. I also recently installed PBoost, but haven't been using it. I seem to remember hearing that P4 started to get sick once the runtime directory reached a certain number of folders or something... could that be it? I'd be really grateful if anyone who's encountered my problem could give me some advice. Please don't tell me that I have to reinstall the whole thing and rebuild my entire Runtime!!!??? Thanks! Morph
