How can I stop pop-ups of script error
messages?

When you’re surfi ng the web, there are times when some of the scripts don’t run correctly and you encounter lots of script errors.
You can turn off these useless script error messages from popping up by doing the following:
Click on “Tools | Internet Options |
Advanced” Now click the checkbox labeled
“Disable script debugging”. Uncheck the
checkbox labeled “Display a notifi cation for
every script error”.

Note: Please do this if you are absolutely sure that you don’t want the script errornotifi cation; though the error notifi cation doesn’t affect the page loading and execution, users who want to test or de-bug a web page should have the notifi cation turned on.
