What is this and how do I fix it? Thanks!
Internet explore script error line 766 char 18 access denied code 0 url about:blank

This keeps coming up in my son's computer home school curriculum. We've used this curriculum all year with no problems with this script error until now.

a) Disable script error display in IE using the steps described in the thread https://www.askmehelpdesk.com/internet-web/internet-explorer-stop-running-script-73040.html

b) Cause of the problem may be some new security patch

c) See if any upgrade to your son's curriculum is available
