            }
        }

        // clear the buffers
        glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

        // draw...
        glBegin(GL_POLYGON);
            glVertex3f (0.25, 0.25, 0.0);
            glVertex3f (0.75, 0.25, 0.0);
            glVertex3f (0.75, 0.75, 0.0);
            glVertex3f (0.25, 0.75, 0.0);
        glEnd();



        // end the current frame (internally swaps the front and back buffers)
        window.display();
    }

    // release resources...

    return 0;
}

The above code is displaying junk window title, not "OpenGL".
What did I do wrong?
I'm using 2.0

You're linking against the release libraries (without the '-d' postfix) but you're compile your application as debug. You can't mix release and debug with SFML. ;)

I strongly advice you against the use of #pragma comment linker commands, linking settings are not part of C++ code but are properties of the project, thus you should put them into the project settings, as explained in the official tutorial. ;)

Thanks, i solved the problem.

I noticed that I didn't have to call glFlush() to render

does window.display() include glFlush()?
