Help with Drupal.behaviors and AJAX refresh
Well it seems I have found a solution :-)

I needed to add 'context' to the function of border adding itself

so this

 $(".moviescreenss").each(function () {


becomes this

 $(".moviescreenss",context).each(function () {


and now it seems to work fine :-)

Still need to see if I can make the whole code more efficient, I'll go to stackoverflow with this and update here if I get anything better
