Odd indeed. I just sent Eovia an email and got a prompt human response. Unfortunately I haven't been able to create a reproducible problem (aka crashes every time I hit THIS button). Loaded and ran smoothly in 9.1, all functions active with exception of the background image in modelling window -- and odd unexplained crashes when working in Vertex modeller. Seems to run smoothly in Jaguar but, alas, my underpowered PowerBook does not. Oddly enough, the pre-release Beta never had a problem. I've asked Eovia to let me continue using that as a stop-gap! Oh, yeah...won't load at all on an old Sonnet-Accelerated PowerMac running 8.6 But who is surprised there? Carrara2 still runs, tho.
