Web page? Debugging is one of the most annoying so-called features in IE. If there’s a bug in a Web page, that is, if the person who created the Web page made a mistake, why would you want to fix it? Relax if you’re worried that you are at fault for triggering these unwanted Debug messages. You didn’t do anything. The messages occur because IE can’t figure out how to read a Web page. Fortunately, it’s easy to turn the error message off, permanently: Start Internet Explorer. Choose Tools ➪ Internet Options ➪ Advanced. The Internet Options dialog box appears. In the "Internet Options" dialog box, under the "Advanced" tab, Select the "Disable Script Debugging" check box (if it’s not selected by default), in the "Browsing" section. It’s probably not selected, and that’s why you see the Do You Wish to Debug? messages. Deselect the "Display a Notification About Every Script Error" check box. Click on "Apply" and then "OK". You’ll never be asked to debug a script again.
