Hi Kendy, Cédric, In my last build of master (Version 4.0.0.0.alpha1+ (Build ID: 9bfa09273ea0b7c9a351802d105230930951b90)), the styles preview does not work anymore. It worked yesterday. Perhaps some side effect of a recent commit. Best regards. JBF -- Seuls des formats ouverts peuvent assurer la pérennité de vos documents.
