jquery uploadify and oncomplete

Question

Hi i am using uploadify in my cms.. basically, it opens in a popup window you upload.. that part all works.. however when i try to run a function in the parent window to refresh a panel to show new images it just freezes...

 onComplete: function(event, queueID, fileObj, response, data) {
          {
                window.opener.document.refreshFM(); 
    }

this is the onComplete function..

any ideas? thanks A
