"A script on this page is causing internet explorer to run slowly"

I left work on Friday and my Search worked fine. This morning, a co-worker reported that he gets an error when he uses the search functionality.

I found this MS article: http://support.microsoft.com/kb/175500.

I'm putting this in the forum so that if someone else runs into this, it's not with the WebHelp system - it's an IE setting.

But I am very curious what - all of sudden - would have triggered this.
