suppress Error Loading alerts

I have the editor setup w/ javascript and linked in through my script when the page loads. If a user goes to a page which has an instance of an editor attached to a field and then quickly leaves (follows a link elsewhere) they get an alert for "error loading http://blah/blah/foo.js". Is there anyway to suppress these alerts? I don't want them showing up, and the user really doesn't need to know that a file didn't get loaded since they are leaving the page anyways.

thanks!
