Thanks for the reply, Georg. I've already sent a couple of posts complaining that I suddenly lost the display of a couple of greek characters (like \epsilon and \varrho) and several math symbols (like \int, \partial, \to, etc). That happens only in MathEd mode. Instant Preview is fine.
The problem appears in all LyX versions I tested (1.3.6 - 1.4.0) in my laptop that runs Mandriva LE 2006. My fedora 4 boxes are ok. It seems to me that this bug appeared after I imported the TrueType fonts from the windows partition using the automatic engine provided by drakkonf, but I'm not 100% sure that this is the source of the problem. I thought that I could remedy the problem changing the characters codes in the symbols file, but this file has not changed after I imported the TrueType fonts. In fact, this file seems to be exactly the same, irrespective of LyX version and target distribution. So, I think this is really useless. I'm somewhat at a loss here. Do you have any suggestion about where I could look for the source of the problem? Thanks.
