Did you ever find the cause of this problem? I have the latest IE, Firefox, and Safari. I cant view Paypal in any of them. I get a few readable letters and the reast is question matks or small empty squares, depending on the browser. In Firefox I can view the page if I first click "translate this page with bablefish" but I cannot take any actions. I have no reference to paypal in the above mentioned "Hosts" file.
Thanks,
Alan
