Ok - I think I've figured it out. Basically some font sizes eg (Helevetica 13,14) Just dont display pretty. I'm using helvetica 15 which looks crisp. there's just a bit of trial and error involved in getting the right display.

Thanks, I just ran into exactly the same fuzzy glitch.

Helvetica 19 works great too.
