I've downloaded the control again. I created a test application and tested it. It works fine. So I copied the control files to an existing site and created a test page with a control and get the same result. test page code below:
<%
@ Page Language="VB" %>
<%
@ Register Assembly="CuteEditor" Namespace="CuteEditor" TagPrefix="CE" %>
