When using the RadMaskedTextBox control with the following setup, copy and paste in IE browsers (tested on IE11) does not work (nothing happens).

 <table width="100%" cellpadding="5px" cellspacing="5px" border="0px">
                                <tr>
                                    <td width="50%" align="right" valign="top">
                                        <asp:Label ID="lbllicenseStateID" runat="server" EnableViewState="False" Text="driver&#8217;s license or<br> state identification number: <br>(two letters and six numbers)" meta:resourcekey="lbllicenseStateIDResource1" AssociatedControlID="licenseStateID"></asp:Label>
                                    </td>
                                    <td width="50%" valign="middle">

                                    </td>
                                </tr>
