This bug causes the pop-up to appear with the top in the center of the screen. This appears to on affect IE...
In the "_center_overlay()" and "_showContent()" functions, there should be a "var" in front of the "projectedTop" lines...
The issue is that the projectedTop variable get used twice and IE thinks that the name-space is the same (not a local variable.)
----- function _showContent(){ $('.pp_loaderIcon').hide();
// Calculate the opened top position of the pic holder var projectedTop = scroll_pos['scrollTop'] + ((windowHeight/2) - (pp_dimensions['containerHeight']/2)); -----
