How to fix the drag and drop bug in IE?
<p>I am working on the drag and drop element function and have problem on IE.</p>

<p>The dragability works but if I drag my items to the edge of the browser, the contents should be scroll up or down automatically (works in Chrome, FF).
In IE, the element and the dragged element will stock to the edge of the browser without scrolling. Is this IE default behaviors? Are there anyone here can help me out? Thanks.</p>
