Try manually typing in http://www. before the address? (Random technobabble on the topic here. Basically at some point, "www" stop being necessary for most websites so whether or not the browser automatically assumes you need it depends on the browser and, well, the site itself. People are smart enough to link their sites properly and browsers are smart enough to follow paths correctly, but if you're manually typing site urls in... yeah, some of them do require "www" and browsers no longer automatically supply that behind the fold. It's kind of a security thing? I dunno. )
