Please check your Editor.ChangeAbsoluteURLsToRelative Property setting.

By default Internet Explorer converts all URLs in hyperlinks (anchor tags) and images (img tags) to absolute URLs.

When this property is set to true (the default), CuteEditor strips out the local server name from all A and IMG tags if the hostname in the URL matches the current hostname.
