Re: [Freeglut-developer] Menu Deactivation

[Jason W. <jas...@gm...>]

I can confirm that a version of Nate Robin's windows GLUT, which uses
(Windows pop-up menus instead of custom OpenGL windows), definitely
dismisses the menu immediately on clicking.

To test I just did a sleep for 10 seconds in the menu callback.
Application became unresponsive, but the menu disappeared first.  The
same test in FreeGLUT keeps the menu open.
