Primewire has a funky way of redirecting to streaming sites without ever actually leaving their site so they can inject an ad banner on every page. In Maxthon whatever rule is blocking the banner is causing the body/html to render the height of the banner. Examples:
http://www.primewire.ag/external.php?ti ... loggedin=0
