Hi Manfred,
Your email and discussion with Ioannis have sparked a bunch of changes to the windows side of things, menus are working much nicer there now. But that doesn't help you at all.
So list, does anyone have an idea about the Linux side of things what happened to the menus? And maybe even a fix?
Manfred, should you have foun out something by now, please do let us know.

Do you have any idea what could be causing the problem described below?
Feel free to forward the mail to the mailing list.

Subject: incompatibility between freeglut-2.6 and freeglut-2.8 with menus

I've observed that the (popup) menu from cgx stopped working after 
upgrading from freeglut-2.6 to freeglut-2.8.
The code works with glut-3.5, freeglut-2.4, freeglut-2.6.
With freeglut-2.8 it stopped working.
I've tested with freeglut-2.8.0 from Fedora FC17.
As far as I can see, it's based onfreeglut-2.8.0.tar.gz from Jan 2012 
without any changes.
(1 patch that affects the -L flags for the demos)

Are there any known bugs?
Are any special initializations required?

Attached is a test case: freeglut-2.6 shows a menu, freeglut-2.8 doesn't.
