What platform and OS? I tried it under my usual OS 9.1 and no dice...I booted up in Jaguar instead (stock configuration) and it worked like a charm. I can't swear this isn't something to do with OpenGL -- which I recall Eovia mentioning is still being worked on. It is so nice in the Vertex modeller, tho, I hope they put it in the spline, too. Heck, in all the windows!
