256986 Description of the Microsoft Windows registry
When you try to quit Microsoft Internet Explorer 6, the program may stop responding. Additionally, an access violation may occur in Msxml3.dll, and you may receive an "Access Violation (0xC0000005 exception)" error message.
This problem may occur after you view a Web site that has XML elements in its HTML code. When you quit Internet Explorer, it unloads Msxml3.dll. When Msxml3.dll is unloaded, it frees any memory that was used to load the XML components on the Web page. However, Internet Explorer may try to access these empty memory locations. Therefore, Internet Explorer may crash.
