I got a suggestion for you.... check out my website... click on the Internet Explorer tab... if you do not want to go there, i have a small post about tab problems... here it is...
Some people that upgraded to Internet Explorer 8 are experiencing problems with their tabs not working properly and taking forever for them to load. This is mostly known to be an error with actprxy.dll not installing properly during the Internet Explorer upgrade. No worries, fixing this issue is extremely easy. All you need to do, is go to your start menu search box, type in cmd, right click cmd, and run as administrator. Once cmd comes up, simply type: regsvr32 actxprxy.dll . you should then get a little notification on-screen that says DllregisterServer in actxprxy.dll succeeded. All you need to do now, is reboot and test IE8.
hope this helps you, and be free to search my site for cool things to do to your computer.
