Dear list, Just let you know that underscore.sty has a problem that causes \includegraphics{"filename_with_underscore"} to fail. Try it by
1. lyx->new document 2. preamble add 'usepackage{underscore} 3. insert a figure, compile. Even if a latex file can be compiled directly, it will fail under lyx because of the way lyx handles figures. Cheers, Bo
