Delete 'Results posted successfully' popup

Hi

I've been working on creating a course and am getting pretty close to finishing it but have one real showstopper that I'm struggling to find an answer for.

Results for the course go to a local server, and the email address and name are passed in as variables so the user doesn't see a popup for those, however they continue to see the 'Results posted successfully' popup, which looks awful and isn't needed.

Does anybody know how to get rid of this? I found a thread detailing how to edit it, but that won't help

Thanks
