Just started a new site. Developed the graphics, imported into Styles, set the type style for the buttons. Started the layout. Now the type on the buttons looks just fine in page view. Switch to Preview and the type is broken up badly, so much as to be unreadable. Do a local publish and check. Same thing - crap. OK, forget about v12 and re-do the site in v11. Same result! Now I've never had this problem in v11 before. Tried it on 2 different machines, an XP desktop and a Win 7 laptop. Same result. Looks fine in Page View, crap in Preview and published.
