Erm....okay, so you don't like Microsoft? Just kidding - actually, I've worked with Java for the past five years, so I really have no business commenting on .Net and all that. And I only know Longhorn by name, but you make it sound like a creation of Baal (oh, wait...) Naaah, I'll stick with my company-provided W2K, thank you very much. Won't upgrade until physically forced to! ;-) But, in order to keep the thread on-topic (don't wan't Guitta on our backs), I have to report that changing the port numbers actually helped a lot! I've rendered 'Danish Spring', 'Amazon' and 'Hospital' without a hitch! Animations are still buggy - 'Mount Phoul' crashed VuePro within a minute, but I'm a lot more confident I'll get it working now. Is this another case of RTFM? I could have sworn...
