FCKEditor Asp.net Ajax ModalPopupExtender, popup windows bu

I'm using ASP.NET 3.5 with Ajax Extensions.

I want the editor to open up when a link is clicked in a Modal Dialog, I have it contained in a Panel
like this

<asp:Panel ID="Panel1" runat="server" CssClass="modalPopup" Style="display: none;"
Width="600px">
<FCKeditorV2:FCKeditor ID="FCKeditor1" runat="server"></FCKeditorV2:FCKeditor>
<asp:Button ID="ButtonOK" runat="server" Text="OK" CausesValidation="false" />
</asp:Panel>
<asp:LinkButton ID="LinkButtonWhatsThis" runat="server" CausesValidation="False">Whats this?</asp:LinkButton>
<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="LinkButtonWhatsThis"
PopupControlID="Panel1" BackgroundCssClass="modalBackground" CancelControlID="ButtonOK">
</cc1:ModalPopupExtender>

This all works great, the editor is functioning, however, if you chooose any thing which pops up a window, such as a "Font"
they popup *BEHIND* the editor, so it's not usable?

Is there some way to reparent the editor or some other workaround?
