It seems that DragPanel is not working on IE10 (windows 8 x64).
For example the official sample (just try it yourself : [http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/DragPanel/DragPanel.aspx](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).
Comments: You might try this fix explained in another work item which describes the same type of issue. http://ajaxcontroltoolkit.codeplex.com/workitem/27369
