Hi Capitolimpact,
The both editor can handle the same html content, and the Rich TextEditor will shows the same format as the CuteEditor. What you need to do just ensure that they has set the same settings.
Just some examples.
Like property "EditCompleteDocument", if you have set this in CuteEditor, but did not set it for the new RichTextEditor. Then the RichTextEditor may remove the <html> and <body> target. Because both of them does not support the full document by default.
And property "URLType", if you use "absolute" in CuteEditor, but did not set the same in RichTextEditor, the RichTextEditor may may the relative paht.
If you uisng some special settings for the CuteEditor and do not know what is the new name in RichTextEditor, please list them here, I will show it to you one by one.
Regards,
Ken
