All of a sudden I keep getting this message when viewing on the web: “A script on this page is causing IE to run slowly. If it continues to run, your computer might become unresponsive”. How do I fix it?
If this is happening on more than one or two sites, you can change the time-out value in Internet Explorer. (Versions 4.0 and up)
Microsoft does offer a “Fix it for me” option on their support site.  You can click on the icon for Microsoft Fix it 50403.
You’ll get this window.
A step-by-step Wizard will walk you through the process. If you are not working on the computer with the issues, you can save the Fix it solution to a flash drive or CD and run it on the computer with the issue.
