A Blug in ModalPopup

The ModalPopup will be covered by dropdownlist if there is dropdownlist in ContentTemplate

<atlas:UpdatePanel runat=server ID=update1 > <ContentTemplate><asp:DropDownList ID=zoneType runat=server Width="132px" ><asp:ListItem Value=1>other</asp:ListItem></asp:DropDownList>

      ....

This is discussed in a couple of other posts in this forum (please search for details). Briefly, IE creates actual window controls for stuff like this and they aren't subject to the normal layering rules of the page.
