I managed to write a nice Lyx layout for the MNRAS articles and everything works fine (I have some problems, but maybe I'll ask later). When I compile an article, I receive an error: Error in MakeLatexFile: You should not mix title layouts with normal ones. Note: overstrike characters may be incorrect. The article looks absolutely perfect, so it's not a big problem, but I'd like to knwo what's wrong. Thanks, Stefano
