Dear Rick,
I use WC 6.05 and suddenly get a strange problem with DatePicker.
If I set AutoPostBack="" the calendar close when I click on a day (it is right).
If I set AutoPostBack="True" the calendar does not close when I click on a day (I have to click on Close button) and postback does not run.
In another similar webpage DatePicker runs AutoPostBack, but I am not able to understand what is wrong here.
Thank you very much for support

               <table>
                    <tr>
                        <td>
                            <ww:wwDatePicker ID="txtDaData" runat="server" DateFormat="dd-mm-yy" width="80px" 
                            ButtonImage="~/images/calendar.gif" AutoPostBack="True" Change="" ></ww:wwDatePicker>
                        </td>
                    </tr>
               </table>
  

Solved after a lot of experimentation.
