Well, I wouldn't blame P5's crashing on a "buggy OS'. OS 10.2.6 is far from buggy, yes I know it has a few, but Panther is sure to have more. This sounds like a Poser issue. If P5 used OpenGL, I might suspect a video issue. OSX has been rock solid for most people that I talk to and generally if one app is crashing allot and behaving badly, it is likely the apps fault not the OS. regards, Paul
