Le navigateur de WAMP se définit dans un fichier de configuration de WAMP du style wampmanager.ini ou quelque chose dans le genre. ;) Fier d'être Normand!

Merci pour ta réponse

je n'ai rien modifié au fichier C:\wamp\wampmanager.ini
et pourtant cela remarche: la page http://localhost/ est de nouveau accessible , je peux tester mes pages web

je suppose que pour forcer WampServer à utiliser IE
il faudrait agir sur une de ces lignes, mais laquelle ?
