Toon always causes Carrara to shut down (no error messages) when I try to render a TIFF image at 3200X2400. Any fix for this? I can't assign more RAM to the Toon extension AFAIK. 1600X1200 isn't big enough for an 18X24 poster at 150 dpi, according to Kinko's. (Mac OS 9.0.4, G3, 400 MHz, 220 MB physical RAM for Carrara.)
