I dont really have any good tips for you.. but try both IE6 and IE7.... I hate getting things to work that want to use IE... like when getting Star Trek Online to work correctly their whole launcher patcher is through IE... was pain to finally get it all working completely right... I finally got it all good using IE7, whereas IE6 had many problems. full IE7 doesn't usually run as good as IE6, but if your only using the IE rendering engine, its a different story.
