CKEditor disappears after PostBack

I am using CKEditor within my UpdatePanel

 <CKEditor:CKEditorControl ID="CKEditor1" ClientIDMode="Static" Height="400" Width="800" EnableViewState="true" 
                                BasePath="../ckeditor/" runat="server"></CKEditor:CKEditorControl>

and I have a PostbackTrigger for my updatePanel to download a file. But when the control with the PostBackTrigger is clicked, the editor disappears. Any thoughts?
