It works perfectly (AFAICS) here. >>> Btw. where is the environment list "known_math_environments" stored? > > There is only this line: > > CommandMap known_math_environments; > > But I want to know what is in the list named > "known_math_environments". I expect there environments like "alignat". This stuff is in the lib/syntax.default file (more precisely, enclosed in \begin{mathenvironments}...\end{mathenvironments}). It may be that tex2lyx does not manage to read the file. Did you move the binary? You could also try to do a full rebuild to make sure everything is alright. JMarc
