Since I started to write my PhD, I selected the frenchb language in the Document layout. It worked fine until now. I made some corrections to the report (nor on the structure, neither on the configuration) but it seems that Lyx just don't care of my choice: when I compile the document, all the titles are in english (Contents and so on...).
I think an example document should be appropriated but I have first to create a short one (can't send the entire report...). Someone had this problem (the solution would be much better...)? Could it be related with my recent installation of bibtopic and bibtex packages? Jean-Philippe
