Why does the browser display the slow script warning?

Submitted by: Administrator
When JavaScript on your browser is running but, it is not responding from a long time, then browser may display a warning message and give the user an option to terminate the script. Example, while loading a video application on Internet Explorer 8.0, it displays Yes/No dialog message like this:
Stop running this script?
A script on this page is causing Internet Explorer to run slowly.
If it continues to run, your computer might become unresponsive.
