No problem, thanks for the info. Well, I thought maybe it was an Nvidia thing, but you say the ATI machine doesn't work either. Hmmmmm ... my other machines have an ASUS and and ATI respecitively, and they work fine. Both have less horsepower and less memory. One is even running Win95. Bizarre. I've talked to Curious tech support and they are pretty much clueless. If anyone else reading this experiences this problem, please do a quick post here to let me know. Mine usually stops at frame 1 or frame 9 every time. WEIRD! Maybe someone at Zygote knows. -Tim
