another thought is for folks to post their version numbers on 
/everything/ (OS, freeglut, Lisp, etc etc etc) to help narrow things 
down. Knowing Frank's successful set-up (all those version numbers)

Yeah, that's how I work. If you have not punted altogether on this, I think the first thing to check is the Freeglut C demos. UFFI agrees with you that the Lisp string can be passed raw to glut-create-window, so it is hard to see what you could be doing wrong.
