I've tried it with preview set to wireframe and had problems; I've removed all extraneous objects, both through the menu and by manual examination; I've used software and OpenGL preview, I've made sure nothing else was open except Carrara, and that texture spooling is running. It seems to be a problem specifically with Poser native import. (BTW, I'm a dual G4, 2GM memory, 128M Radeon 9800 Pro, and don't have this problem with more complicated, non-Poser files...) I suggested it might be Mac only because I haven't seen any PC users particularly complaining about the issue. Granted I jumped to a conclusion...
