recently, i was getting IE UDF errors when i was using functions like '_IEAction($object,"click")' in Win8. i searched forum and saw people that had same issues with me. i installed xp in virtualbox and tried my script there. woala! it is working. then i found this solve: - press ALT in IE to see top menus. - go to Tools > Compatibility View Settings > open "set Compatibility View for all web sites" (i dont know its english exactly) if u do that, you can use IE UDF in win7, win8
