Le swfobject.js ainsi que d'autres fichiers javascript sont stockes dans un autre dossier.
Jusqu'a recemment tout marchait tres bien et depuis une update recente de flash player certains boutons ne fonctionnent plus, notamment Next. Quand je regarde le log je vois que l'appel de swfFile.GotoFrame() echoue et j'obtiens le message suivant : "Error calling method on NPObject!". Je suis alle sur de nombreux forums ou d'autres personnes ont le meme probleme que moi et certains disent qu'il s'agirait d'un probleme de securite. J'ai essaye de mettre "allowScriptAccess" a "always" comme ils le preconisent mais ca ne change rien. Je re-precise que je ne suis pas developpeur web alors essayez d'y aller lentement si vous avez des explications techniques a me donner :mrgreen:
