Chris - Thanks for replying. I too wondered if the advancement was being calculated from the glyph's origin instead of (0,0) but there are two strikes against that theory. 1) The docs clearly state that the advancement starts from (0,0) not the glyph's origin. 2) I'm seeing problems even with glyphs whose origin is to the right of (0,0).
