Hi, Sorry for my english
Scenario: a scroll gallery: a draggable div move another div  

<div id="draggableDiv">....
<div id="spot" style="overflow:hidden">
    <div id="slaveDiv">
        <img id=1><img id=2>....
    </div>
</div>

var dragOption = new Object();
dragOption.axis =
'x';
dragOption.drag=dragCallBack;
...

//moving slaveDiv by draggableDiv drag event
function dragCallBack(event, ui){ 
      slaveDiv.css(
'left', 0 - draggableDiv.position().left); 
      
// draggableDiv.position();// USE TO SPEED UP IE8!
}

While explorer executing the 'drag' callback function to set css('left'...) of another dom object
the draggable movement is not smart...corrupted, but, if after css(...) instruction i add draggedDiv.position() it speedup and work fine!...

...what you all think about? Bye!
