Well, just save your .ps, .pdf or .dvi and you should be fine. Note that even stock latex packages may get bug fixes or tweaks that will change the layout slightly. And, on top of that, in a decade or so there will be hopefully a new latex and everybody will be busily porting their documents to it (hopefully, too). Expecting lyx to handle that kind of stuff is not very reasonable methinks. Kuba
