What ones? I'd guess most LyX users do like I do and create new PDFs continually while their PDF viewer is still open. Some PDF viewers have behaviour to reload updated PDFs automatically (which is just the opposite of forcing a file lock). My experience is with evince, xpdf, epdfview, gv, ggv, gpdf, and others and I don't recall this locking issue. Also how is the file lock done? File locking makes a lot of assumptions and often doesn't work on some systems for some file systems. A reliable way of doing file locking is to create a lock file (a separate dummy file); if that is the case, what is it called? Attempting to google for this topic mostly turns up about PDFs that are protected so others can't view without authenticating. But now I read that Adobe reader locks files. (I don't use Adobe.) So I guess the solution is not to use Adobe :) Jeremy C. Reed
