Same here:

"TypeError: window.createPopup is not a function"

please fix this soon. I have to revert my update because of this bug.

And could you please provice a different method for delivering hotfixes? It always takes an hour to install the whole package. Could you prepare just the assemblies as well?

Matt, I've a workaround which works (not perfectly, but it works). It creates the removed function to the document object if it doesn't exist:

if (!document.getBoxObjectFor) {
   document.getBoxObjectFor = function(el) { 
      var pos = {};
      pos.x = el.offsetLeft;
      pos.y = el.offsetTop;
      parent = el.offsetParent;
      if (parent != el) {
           while (parent) {
               pos.x += parent.offsetLeft;
               pos.y += parent.offsetTop;
               parent = parent.offsetParent;
           }
      }
                
      parent = el.offsetParent;
      while (parent && parent != document.body) {
         pos.x -= parent.scrollLeft;                    
         if (parent.tagName != 'TR') {
             pos.y -= parent.scrollTop;
         }
         parent = parent.offsetParent;
      }
      return pos;
   };          
 }

I hope that IS publishes a hotfix soon though.
