No "X" on popup

Hey,

Thanks for setting it up. I was not entirely able to pinpoint the source of the problem but I suspect that it is some kind of jQuery compatibility issue along with another plugin. Because not only does the close button not show, the onscroll and onclick handlers are not attached also.

Could be a compatibility issue with the latest jQuery (as you have the jQuery updater installed) or a conflict with another plugin maybe), but unfortunately I was not able to tell.
