try saving your scene, closing Poser, then starting Poser, load the scene, and render.

The memory thing....I used to have virtual + real mem equal to about 2gig. Then I bought more memory and have 1 gig hard mem...I let XP assign virtual...but since I upgraded to 1 gig, I have no more trouble...plus my hard drive is never activated during render.

Seems to me there was an issue with P4 leaving a lot of stuff in memory...it kept adding up as you added and deleted textures or changed things in a scene..that's why I said above to close and reopen...clear the memory....that cache program should help...plus the Curious memory patch

Humankind has not woven the web of life. We are but one thread within it.
Whatever we do to the web, we do to ourselves. All things are bound together.
