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.

>Does shademodel work for others?

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.
