Would that make an OSX user more likely to want to do an offscreen
render? The way I see it, the offscreen rendering is really only
useful if you want it for a background process like a CGI script in
a web server, or if you wanted to generate a bunch of different views
to look at later, or maybe for an animation, or finally, if you want
to generate really large images for say printing instructions.
Meanwhile, back on the GLUT issue. Apparently, according to the
mac-opengl mailing list, the 10.2.3 update does not yet fix the
keyboard issue, but a new version of the glut sources with a fix
is due "real soon now" at the apple developer site, if you're a
do it yourself type person.
http://developer.apple.com/samplecode/Sample_Code/Graphics_3D/GLUT_for_OS_X.htm
In the meantime someone else on the mailing list suggested another
possible fix that sounds promising. I can't try it myself, but perhaps
someone with an actual Mac could test it.

Hi,
I had the same problem as I use hand made make files instead of Project
Builder for my stuff. I solved it by adding an incantation that runs Rez on
my exectuable, like that:
/Developer/Tools/Rez main.r -o myexecutable
where main.r is a valid Carbon resource file (I used one that was created by
project builder IIRC).
It permits to launch valid cli application that can use the carbon API and
be recognized as such: menu bars, doc icon, etc...
Hope this helps
Sebastien
