Alas--- none of my MACs have any OS-9 apps or Classic OS on them. As I mentioned, OS-9 it doesn't even ship from Apple anymore. And for some reason, freeware code-writers never seem to update their apps --I've been waiting fo 2 years for some of them who post on their website that an OS-X version is "coming..." 2 years is a long time to wait... I can only hope that anyone writing for POSER today understands that there is no upward marketability for their product if it's not compatible with the current OS-X user base. And now we're all going to be doing "tiger". So.. hang on to your old OS... You're among the fortunate with respect to this dilema. and -- yes, (for EnglishBob) I only purchase items from Renderosity that say that are MAC comaptible. The Mirrin Product workes perfectly. I hope the Damnation product is fixable. I'll email one of the authors and see... TD
