A newish laptop connecting to the ISP through a standard no frills router will sometimes allow only the browser IE7 to download pages, sometimes allow only the mail handler OE6 to download and send mail and sometimes allow both to work. Other PCs on the same network using the same internet access work without error (so it has to be a problem with the laptop). All Windows security settings at default. Internet Security is F-Secure with the windows firewall disabled. Scans show clear. A HTJ scan shows nothing untoward. Any ideas anyone?
