ajaxtoolkit

Hi,

I'm trying to use the AjaxToolkit's ModalPopupExtender, but it doesn't work. In fact, as soon as it opens, it's getting closed. So I can see that it is rendered, but it's getting closed in the second.

I tried that with IE6 and Firefox 3, it does the samething.

Here's the code:

<AjaxControlToolkit:ModalPopupExtender ID="ModalPopupExtender1" TargetControlID="ButtonTarget" PopupControlID="Panel1" OkControlID="ButtonOk" CancelControlID="ButtonCancel" BackgroundCssClass="modal-background" runat="server">
</AjaxControlToolkit:ModalPopupExtender>

<asp:Panel ID="Panel1" Style="display: none;" runat="server">
<%-- some stuff... --%>
</asp:Panel>
