Can't Drag and Drop Conditions & Jquery Center Pop Up

I have just installed Pop up! and am trying to use it with wordpress 3.6 and woo commerce 2.0.13.

I can't seem to drag and drop the conditions at all. It just highlights the text instead. I am have used both chrome, and firefox and the problem happens on both browsers.
