Hmmm... I remember doing the NeHe stuff, and I've never seen wglUseFontBitmaps before... maybe the lesson was rewritten, but the text drawing code there is completely alien to me... Except For The Way He Capitalizes Every Word In The Comments For No Apparent Reason...
Edit: WTF, lesson 13 seems to have been completely rewritten since I learned it.
Edit II: So yeah, I have no idea how that code works, and I've never done anything with glRasterPos in my life. If it worked like the old one did (which I doubt it does), I would have said to make sure that your projection matrix is screen-space ortho (that is, do glOrtho(0, width, 0, height, -1, 1) (but being sure to have the correct matrix mode)). But since it's not the same, I doubt that would help / be at all relevant. Sorry.
