Tim,
The almost certain reason Jonathan is getting protection faults is that fractint is way too big to fit into the medium memory model without overlays. The current DOS version works with the medium model only because we gave a whole lot of thought and shoe-horned it in. Bert had to do something similar with Winfract, but it was easier then because Fractint was smaller. But when Jonathan merged the current sources, Bert's overlay scheme probably broke.
I don't see any evidence of an overlay scheme, but I could just not know where to look. My brief reading on the subject seems to indicate that with the medium model, Windows takes care of the overlay functions. Jonathan
