Thanks, I'll upgrade right away. It probably doesn't help that my work flow involves keeping Vue, Poser and Photoshop all open at the same time! 2 gig it is. A nice feature in Bryce, by the way, is that it switches to wireframe boxes automatically when needed when moving the camera, and then switches back when the movement stops. It means that navigation is very quick and responsive and precise with huge complex scenes. Improving the preview handling in Vue is something e-on could address with profit.
