Bonjour,
J'ai un problème sous internet explorer, si je clique sur mon raccourci internet explorer pour ouvrir yahoo.fr par exemple , la page se lance mais il arrive parfois que rien ne s'affiche.
je re clique sur internet explorer et là ça marche
avant j'avais pas ce soucis
De plus si j'ouvre un lien a partir de mes favoris idem si ça marche pas je suis oblilgé de faire ça une 2nde fois.
