Reorder list not working in Chrome

.net 4.5,  latest december version of the ajax toolkit.  Works fine in IE,  but in chrome it just drags but does do anything.  In Chrome also,  the css styles dont match those in IE (which works)

any clues?

</asp:Panel><div class="reorderListDemo"><asp:ReorderList ID="ReorderListAuthors" runat="server"
                    DataKeyField="AuthorsID"
                    DataSourceID="SqlDataSourceAuthors"
                    PostBackOnReorder="True"
                    CssClass="ReorderImages"
                    AllowReorder="true"
                    CallbackCssStyle="callbackStyle"
                    SortOrderField="sort"
                    DataMember="DefaultView"
