By this you mean - did the Flight Crew and W3C come up without any errors? Yes, they both did. I am guessing that SOMEWHERE there is some sort of hidden code, but I can't find it. All the styles point to the embedded font that I want, but it just keeps coming up with a different font. What is even more strange is that I can't find a listing anywhere for the font that is coming up - else I would just change it! I know that the fonts are in the right place, etc, because the italics come up in the right font - just not the regular normal font....
