I had trouble with Stephanie locking up my machine when rendering (but it was not always reproducible) Finally, I shrank my textures down to 1/2 their original size (had planned on doing that any way, don't need the larger files just yet) and it hasn't been a problem since. I've used other textures of the same size, but perhaps these have a higher color depth or the bump map is considerable larger (mine were the daz hi res maps) eric
