Well for what it's worth I touched Windows XP with my own hands, and although it's got its own specific quirks, it essentially fixed the same type of rendering problems. My first test was to put 4 Vicky's with Daz's high rez textures, a few Vicky's with StefyZZ's textures and a couple of Mike in the same scene. Rendered with no problem. Haven't had Poser lock up since then. I always feel the need to apololgize to Curious Labs, I was convinced that Poser was the culprit, when in fact it was Windows that caused my Poser woes.
