OK, maybe I was a bit rushed there...
I still have the problem with Firefox.
Also, the folder view to the left is blank - there are the buttons at the bottom: Mail, Folder, Contact and BBS.
Selecting Mail & Folder displays the contents in the main left window, but nothing in right. Selecting Contact, gives: Contact Group Lis, Manage Contact Group and Import Contacts"
I have tried accessing the online mail with Opera, but it just gets to "Loading, please wait" and doesn't do much else.
