make sure that your browser settings are so that your browser will not auto-complete entries int he address bar. For instance, when I enter google.com, it will probably add a www., if not the entire thing (http://www.google.com), and the way you can stop this is (in most browsers), is by turning off auto-complete (some browsers call it differently). You may want to turn off automatic domain guesser, which will fill in items like .com, .org, .biz, .net, etc., and this may solve your problem too. Some browsers include these options to turn it off, including Mozilla, Mozilla Firefox, Opera, (Perhaps Internet explorer), and more. Check your settings.
