jquery dialog: dragging dialog with iframe inside

Question

When dragging a jquery dialog with an iframe inside , the drag stops if the mouse goes over the frame contents while dragging. It seems that the iframe takes automatically the focus. is there any way to prevent this and make drag normal?

var iframe=document.createElement('IFRAME');    
$(div).append(iframe)
       .dialog();

Answer 1

from naugtur suggestion i found this good working solution:

dragStart:function(){
    var divt=document.createElement('div');
    $(divt).attr('id','tempdragdiv');
     divt.style.height='93%';
    divt.style.width='100%';
    $(divt).css('position','absolute').css('left','0')  .css('top','0');                    
    $(div).append(divt);//div where is iframe
    },
    dragStop:function(){
        $('#tempdragdiv').remove();
    }

Answer 2

have you tried setting a z-index for the iframe?

var iframe=document.createElement('IFRAME');    
iframe.css('z-index', '-999');
$(div).append(iframe)
       .dialog();

It's just my guess, but I'd try covering everything with a transparent div 100% width&height while dragging and assuring it's above iframes and under the dragged thingie :)
