The point is to guarantee backward compatibility. In 1.5 you could input a file using macros with '@' without caring and now those documents would not work anymore. So, either we take that into account in lyx2lyx or perform that change. As always, trying to be smart results in being stupid, so, perhaps it would be better to always use \makeatletter \makeatother whenever the preamble is not empty. What do you think? -- Enrico
