Hi all!
I have similar problems with porting an app from Windows and Linux to
Mac OS X (Panther 10.3.5).
See my detailed comments below!

Same for me. I have created an "instrumented" GLUT version that does
some tracing into a log file. The app behaves to the book but I still
get no reaction from the app.
I *do* get a blank window that sets the cursor to the Busy Cursor when
entering the window. When I drag the upper part of the window I can move
it around. Beyond that no response. I do not get to the display
function, i.e. the display callback isn't called. Why? Well, it would be
great to get some help on that one! ;-)

Perfectly OK and strictly obeyed.
Additional info (in case some of you guys have that one around too) :
I am operating from OpenMCL - a freely available Common Lisp
implementation for the Mac.
My questions:
1. Any hints, thoughts, ideas?
2. Anyone interested in my instrumented GLUT version?
THX!
