How to turn off the debug function in IE

Internet Explorer users often receive an dialog box with a message like this ("Error. A Runtime Error has occurred. Do you want to debug?"), which pops up whenever there's a bug in the JavaScript you run into on a website. It makes many people be tired of using IE. This is a function of IE which Microsoft gives us. If you're an IE's user, perhaps you've already know what I'm taking about and you might see that message at less once. When you accepted to debug by clicking Debug, you had no idea what to do with that information. Many users feel annoyed when they see that message box. Fortunately, because it is a function of IE, it's an option, we can turn off it easily.

In either IE6 or IE7, you click the Tools menu > Internet Options, then click the Advanced tab.
Make sure there are check marks next to "Disable Script Debugging (Internet Explorer)" and "Disable Script Debugging (Other)." as you can see in the image. Then the final step you have to do is to uncheck the box next to "Display a notification about every script error."

Each time IE crashes, Window places an error reporting on your computer. You can disable this task too. In Windows XP, you can go to the Control Panel > choose System, continue by clicking Advanced tab, then click "Error Reporting" at the bottom of the screen. Click the radio button next to "Disable error reporting." You can turn off "But notify me when critical errors occur" by unchecking it if you want.
