Using jQuery 1.7 .on() and event.stopPropagation to close boxes when clicking in document body
It did work in my Chrome. However, I felt your code was confusing with all those handlers. Let me suggest the following:

$('html').on('click', '.poster', function(e) {

  var target = $(e.target);
  var poster = $(this);      

  if (!poster.hasClass('active')) {
    closeQuickView();
    poster.addClass('active').find('.quick-view').fadeIn(200);
  }
  if (target.hasClass('quick-view') || target.hasClass('image-effect')) e.stopPropagation(); // prevent bubbling and thus closeClickView call below
});

$('html').on('click', closeQuickView);


This way, it's more concise and hopefully clearer what's handling what.

PS: I threw out the conditional '.close' appendage here, nothing wrong with having it in the vanilla HTML I'd say.
