I use the following code and cannot reproduce it:
<%@ Page Language="C#" %>
<%@ Register TagPrefix="CE" Namespace="CuteEditor" Assembly="CuteEditor" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<iframe src ="fullscreen.aspx" width="100%" height="100%">
<p>iframe test</p>
</iframe>
</body>
</html>
Can you post your page code which contains CuteEditor for .NET here? we need reproduce this issue.
Regards,
Eric
