DragPanel not working on IE10

Hi,

It seems that DragPanel is not working on IE10 (windows 8 x64).

For exemple the official sample (just try it yourself : http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/DragPanel/DragPanel.aspx) is working well in Chrome and Firefox, but not in IE10 on Windows 8 (the panel just stay in place, and the cursor shows like moving a website image).

Is there a way to make it work without additionnal library ?

Thanks !
