[Freeglut-developer] Menus

One nasty side-effect I noticed recently, consequence of this. I like to 
put a menu trigger "Save" on my Windows, whose callback calls 
glReadPixels and libtiff to save the current image to a file. With 
freeglut, the menu is also saved with the image, which is very annoying. 
So esentially I had to switch to keyboard callbacks to do this.

I like the idea of opening the menu in a separate window, be it rendered 
in OpenGL or native widgets.

Best,
