In my case it was memory. The guys at DAZ/Zygote told me 200MB for anything with lots of textures or the Michael/Vicki characters. On the Mac, I can directly assign enough memory to a task, and the program is happy. When the program is happy, I'm happy. Considering how cheap it is compared to weeks of your time, a stick of RAM seems like a reasonable first assault on the problem of crashes and missing texture maps. Carolly
