Internet Explorer's Script Debugging is a neat feature when you're trying to figure out problems with your own website, but it becomes distracting as it prompts you about problems with other sites.

To disable this feature, load up your Internet Options (via Control Panel or an IE Window) and then click on the Advanced tab. From there under the Browsing section find the Disable Script Debugging (Internet Explorer) box, check it then press the Ok button. From now on whenever you visit a website that has problems with its code, IE will no longer prompt you to debug.
