Hi all!! It's very strange. 1. I write any document, WHITHOUT SAVING IT. 2. I convert to dvi without problems. 3. But, IF I SAVE the document, 4. I obtain 2 errors (both the same): "Missing \begin{document}" The first error, always before the title of the document. What is this? Thanks. Adolfo Pachón. (Lyx is good ;) )
