hopefully you are not using IE7 that had a broken add-ons there. Try right click if this is the case on IE Icon and choose [start or run without add-ons] if it does work properly, then try to disable those add-ons from the Tools>> Mange Add-ons ... if it work then it is fine, most probably it is Adobe flash player who do those ... Good Luck
