hieu.nguyen on "[Plugin: Contact Form 7] How to make Validation Errors NOT disappear on hover."

I have tried high and low, this piece of jquery is located here: wp-content/plugins/contact-form-7/includes/js/scripts.js

$('span.wpcf7-not-valid-tip').mouseover(function() {
				$(this).fadeOut('fast');
			});

However I don't know how to disable this, without hacking this file - which is what I really don't want to do.

Any recommendations?
