mi potete controllare il log, per favore? A volte si aprono pagine all'improvvviso e spesso compare la scritta: si è verificato un errore in internet.exe, la pagina verrà chiusa, a volte anche all'accensione del PC sul desktop nudo, senza neppure un'icona .Oppure: si è verificato un errore in CTF loader, la pag. verrà chiusa etc...etc..
