@laura. Thanks for following up. I have not been able to recreate the issue. I realize that you use the jQuery version of the Event tracking. I need to find out how do you have jQuery setup on your site. Is it through a plugin? or through the template? (and what version of jQuery as well) Let me know so that I can set it up the same way on my test site.
I want you to try one thing for me. Change the Javascript type to Mootools, instead of jQuery. And let me know if you are still having the issue.
