Can anyone confirm this bug?

Download opengl''s MFC source code...

http://www.opengl.org/developers/faqs/technical/mswindows.htm#mswi0160

color is present in debug mode.

But when switched to release mode, color disappears.
however, if you close and open application quickly for a few times, the color will appear...

Any solutions?

I had the same problem when I brought my application from Uni to home.
The problem was with glEnable(GL_TEXTURE_2D) and glClearColor, I needed to call it(actually I call glColor4f(0.0,0.0,0.0,0.0) after I drawn something with color).
So, to draw somwthing with color (line) I call glDisable(GL_TEXTURE_2D); glColor4f(0,0,0,0);
then my color - glColor3f(0.0,1.0,0.0);
then turn textures back on - glEnable(GL_TEXTURE_2D);
