Once, I tried to italicize the name of book in one of my actions, and it worked at first, then suddenly everything at the same level was italicized.. maybe this happened to you?

Try selecting some italicized text, then hit command-I (or select Format, Font, Italic from the menu bar), then click on something else.. does that fix it?

I'm guessing styles are something that are still being worked out in the program.
