Nope - I think so too! I will often go on, bring up all the Eight Boards I generally use as my prowling grounds - and bring up all of the new Posts it has said in my e-mails all in New Winodws; then I go downstairs make a cup of tea and they're ready by the time I finish!
Sometimes even with one Window up MSN thinks it isn't a webpage sometimes because it takes long to load up! I have to refresh the page just to get it up!
Its fast enough though - helps when you're making many posts! you can bring a page up, then reply to another, and once you've replied the other is up and you can start with that!
