Hello.
First of all, thanks for your great plugin!

About bug…
When I go to my page and scroll a little bit down, the popup appears, but if I click to “X” it throws me back to the top of the page. If I click on the gray area – all is ok.

You can check it yourself at http://www.nofakes.net

Waiting for your reply.

ps I know that support only here but I can’t register there via facebook.
