Bonjour,
Bon, rien de mieux.
J'ai installé (non sans difficultés) une version complète de MiKTex 2.9
puis la version 2.3 de Lyx : toujours rien d'utilisable, aucun package
ne semble présent ;
puis la version 2.2.4 de Lyx : tous les packages semblent présents (donc
davantage que sur mon pc précédent),
mais un fichier en classe AMS article conduit aux mêmes erreurs (voir en
gras dans le journal ci-dessous) :
*Invalid UTF-8 byte sequence *
**Missing \begin{document}**
Je vais continuer avec des classes minimales.
Merci tout de même pour l'aide proposée.
JP
