IE usually come with a repair feature. In Add/Remove Programs select Microsoft Internet Explorer the left click the Add/Remove button. The next dialoge box offers three options, choose Repair Internet Explorer and left click on OK and follow the prompts.
If not, try Internet Explorer Fix - General purpose fix for Internet Explorer available at http://windowsxp.mvps.org/IEFIX.htm
Every time I shut down my PC IE gives me a program not responding message. I have to click end now and then the PC will shut down. I'm able to close IE when I'm through browsing but if I'm shutting down the pc I get the error message every time. Are there any IE repair tools? Any thoughts?
