When you try to exit a Web application by clicking the Close button in Internet Explorer, a warning message will be displayed "Are you sure you want to navigate away from this page". After clicking Cancel in the warning message box and further running the application, if you click the Close button in the browser again, Internet Explorer crashes.
Cause: Some add-on program such as SnagIt from TechSmith Corporation has been installed to Internet Explorer.
Solution: Right-click on the Internet Explorer toolbar and disable the add-on program from the popup menu.
