Se guardate scrivo i dati utenti su un file .php

Vengono controllate diverse cose nella compilazione, ma se l'utente ha compilato tutto correttamente, l'ultimo controllo consiste solo nel verificare se il nome utente esiste già o meno....

Il tutto va su Firefox, su Opera, su Safari, mentre su IE mi da come già scelto qualsiasi nome utente digito....all'infinito.....

Se invece sempre su explorer provo a fare il login da utente già registrato, allora non ci sono problemi....

Un amico mi ha detto che capitava anche su certi siti di giochi online coreani che dicevano di utilizzare un browser diverso almeno nella fase di registrazione, una volta registrati, il login funzionava...

E' un problema noto? Qualcuno sa darmi una mano?

Nessuno?

per il momento ho risolto omettendo il controllo sul nome utente.....è un pò una porcata....però alla fine a me interessano i contatti mail per le news più che i nomi utente....

Ho provato la 6, la 7 e la 8... lo fa con tutte... :(

Stesso discorso con gli altri browser....gira correttamente su tutte le versioni più recenti....
