Cannot set pop3 account password in Ubuntu

I cannot download pop3 mail in my Ubuntu client. Other pop3 programs on the same machine work fine and replicas of the same installation work fine in Windows.

The only oddity I have noticed is that it is not possible to type the pop3 password into the account. The cursor stays stuck to the left hand side of the field.

Subject: Ubuntu and pop3

Got over the password problem by creating all the account information on a Windows XP client and replicating. Pop3 access is still not entirely reliable but might relate to a Thomson adsl router being used.
