Nice work on the scene in progress. That purple stuff is pretty odd; that's the first we've seen anyone with that, so it might also be a bug just for the Mac end of things. Maybe a problem writing the PICT format. Steve is so busy, please don't guess he might be reading this thread. If any right now, he's trying to keep up on the patch thread, and also with his voluminous e-mail. So please do report these errors, too -- the purple weirdness and the inability to save to TIFF. You can include a link to this thread so that he can view the example. :)
