Okay, that should be fixed now.  The scs file you sent doesn't have the
spps code in it;  it never sets the page size.  scs2pdf had a default page
size that worked for the old code but not the new stuff.  So fixing the
default helped.  Then I noticed that the page size was being computed
wrong because we used ints instead of floats.  That's all working now,
tested with the scs file you sent me.

I don't know a thing about Windows, but I'll look anyway.

Right, this is what I'm thinking, too.  Almost like event-driven
programming?  Create callbacks, etc., or is that not what you mean?
