When I commented out my implimentation of CEEditor and put yours in place it worked without issue so it seems to be a element i am placing on the editor.  Let me poke around and see if I can identify what it is.  Below is my implimentation that is causing the issue that I commented out and used yours.  

<ce:editor id="tbBCMessage" runat="server" alloweditserversidecode="True" autoconfigure="None"

        bordercolor="DimGray" breakelement="Br" configurationpath="~/CuteSoft_Client/CuteEditor/Configuration/Simple.config"

        urltype="Absolute" Width="680px" EnableAntiSpamEmailEncoder="False" 

            EditorOnPaste="PasteWord"> </ce:editor>
