The Ajax doesn't work for me with the updated patch. I had to go back to the original file which seems to work fine. the only difference i found was this...
 
New file:
//showPopupBlock(msgType, msgText, msgLeft, msgTop);
showMessageBlock(msgType, msgText, messageId);
 
Old file:
showPopupBlock(msgType, msgText, msgLeft, msgTop);
