I put object and embed tag inside a why page and operate on IE

Things are ok.

However when i put object &lifier embed tag inside a page of joomla

I recieve immediately error ( i believe joomla have problem )

__flash__removeCallback(document.getElementById("flash"), "loadData");

Object doesn't support this property or method

it appear like not is available function _expensive_removeCallBack

I've investigated and located documents about problem

I attempt to override that function although not effective. How you can repair it ?
