Hello, Thanks for your quick response.
I don't need Lyx-1.1.6fix4 any more at the moment, so the problem is not urgent any more. However out of curiousity and in case I'll need it again sometime. here are some questions: > Did you set some key mappings in prefs? 1) in my .lyx-1.1.6fix4 there is no preferences file. So I'm assuming this isn't the problem. > information, this happens when lyx tries to load some character set > files. Is it possible that one of these files is corrupted? 2) Where do I find these character set files. are these the fonts I see with gfontsel (one of those, courier elot, is causing me problems). 3) Could there be a mixup between the 1.2 version and the 1.1.6fix4 version I have. (I used: ./configure --with-version-suffix=-1.1.6fix4, to install the 1.1.6fix4 version) 4) When I run Lyx for the first time it works but not on a second time (without deleting the .lyx-1.1.6fix4 directory). Can the possible problems you suggested cause such a behavior? Thanks again, As I said this is no longer urgent, Amir.
