I have checked everything suggested, and even removed the dailup connection and set it up anew. No difference. When I open OE (online) the mail goes straight away, but before it gets the mail in I still get that 'logon - paradise' window. If I cancel it, a larger windows pops up with
"There was a problem logging onto your mail server. Your Password was rejected. Account: 'Paradise', Server: 'pop3.paradise.net.nz', Protocol: POP3, Server Response: '-ERR syntax error', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC92"
It is not a great worry, but I never got this with OE6 under 98se. I am far to inept to start rooting about in the Registry but thanks for the suggestions anyway.
