I have windows 7, IE8, and every time I close a window it says Internet Explorer has stopped working. Check online for a solution or close the program. When I view problem details it says:

Most of these kinds of problems are caused by IE Add-ons. Try starting IE8 without Add-ons and see what happens.

Click on Start then Run, type iexplore -extoff and press Enter.

If the problem does not occur after that then an Add-on is definitely causing it. From IE, click on Tools then Manage Add-ons and start disabling them a few at a time and testing until you find the culprit.
