Hi Prof!
What kind of pop ups have you encountered? The promotional pop up at the front page has your tracking code preembedded into it. All pages on the site have your code preembedded into it when you use your unique trace. This way you can point your traffic at any page you like and still be credited for the downloads and deposits.
I will look through the site again for exit pop ups which may have been left behind by accident.
If you could describe the pop ups for me, it would help me remove them if need be. Thank you for your question.
