Hello all: I have installed lyx (guru's version, newest) onto SUSE 10.0 and SUSE 10.1. The install process ran smoothly, dependency problems were not reported. When I start lyx I get this type of error messages: "The document uses a missing TeX class "article". LyX will not be able to produce output." or: "The document uses a missing TeX class "book". LyX will not be able to produce output." In Document/Settings/Document Class window there are classes listed and all of them marked as unavailable. Why is this and how could I fix it? I am new to lyx. I googled but could not find any usable information. Help or links are welcome! Thanks, IG _____________________________________________________________________ FotoMarket - digitális fotókidolgozás már 25 Ft-tól. http://ad.adverticum.net/b/cl,1,6022,99786,162268/click.prm
