there's alotta folks who could demand a refund, judging by the constant complaints about how unstable poser is, since v. 5. but this is the first time I've actually heard a case where somebody got a refund and is still using poser, apparently. p.s. I'd recommend using xp pro or OS X, and a machine with at least two cores, 2 GB RAM and 256 MB VRAM with openGL. vista might also work but YMMV.
