JavaScript error on the home page

Every time I load the AO home page, I get the following error:

Line: 22
Char: 5
Error: Access is Denied
Code: 0
URL: http://www.burstnet.com/cgi--bin/ads...39/RETURN-CODE

Obviously it's something to do with advertising and Javascript, but it's becoming a real pain now because I can't supress error messages (using a shared machine on a network where preferences aren't all stored means that next time I login to the network, I get the same error message). This error only happens when I log in, not when I visit the home page as a guest.

Greetings All:

Problem fixed, thanks.
