Its a puzzler then, FWIW the following code works for me (I don't 
use GLFW, I have my own window routines, but the opengl-specific 
calls are the same).

Window("window1", WindowState(0,0,200,200), Flag!"Create".yes, 
Flag!"Show".yes);
Window.makeCurrent("window1");

glViewport(0,0,200,200);
glClearColor(0,0,0,1);

bool finish = false;
while (!finish)
{
         glMatrixMode(GL_PROJECTION);
         glLoadIdentity();
         glOrtho(-200, 200, -200, 200, -1, 1);
         glClear( GL_COLOR_BUFFER_BIT );
         glBegin(GL_POLYGON);
             glVertex2d(0, 0);
             glVertex2d(0, 200);
             glVertex2d(200, 200);
             glVertex2d(200, 0);
         glEnd();
         Window().swapBuffers();

         if (Window().keyState().keys[KEY.KC_ESCAPE])
             finish = true;
}

Perhaps something in the GLFW init is modyfying some OpenGL 
defaults or something, you might like to ask on their forum.
