Why do I receive an "Operation aborted" error message when I visit a Web page in Internet Explorer?

This problem occurs because a child container HTML element contains script that tries to modify the parent container element of the child container. The script tries to modify the parent container element by using either the innerHTML method or the appendChild method.

For example, this problem may occur if a DIV element is a child container in a BODY element, and a SCRIPT block in the DIV element tries to modify the BODY element that is a parent container for the DIV element.
