If you are referring to the sample program
"red.c" on page I-5 in the Introduction, 
that is what we refer to as a "documentation
bug", and already has a bug report filed on
it by myself.

Essentially, the call to shademodel(FLAT)
MUST occur AFTER the call to winopen.  If you
call it BEFORE winopen, it will toss its
cookies and die.

I will do my best to get this fixed in the 
next documentation update.
