We did manage to get this to work by editing on a windows machine in IE. However the editor is unusable sometimes in IE too!!

Are you able to reproduce the Safari (Mac) problem with the Default Example of RadEditor? If yes, could you please provide step-by-step instructions how to replicate it on our end, because so far we are unable to replicate it?
You can record your screen with Jing or another screen capture tool and send a video. This will be very helpful for us to see what the problem is and to provide a solution.

Had some real problems again today with the editor. 3 hours to copy and paste a few tables - none of which copied correctly.
Screenshot 09.54 shows what the table should look like.
Screenshot 58.56 shows one copied version.. note the dashed border that could not be removed!
Screenshot 58.44 shows a copied table placed into a table in YOUR editor.
Not very good so far!
Screenshot 56.22 shows the word FIREFOX hyperlinked with a color BLUE
Screenshot 56.38 shows the link turning to purple when I try to type after setting the BLUE color.
Screenshot 57.17 shows the hyperlinked FIREFOX text turning mauve when text is entered after it. The linked FIREFOX text should be BLUE.
This is just a sample of the errors. Your editor did not resize the text and insert rogue coding.

Right now in Safari and IE we are having big problems.
Thanks

Screenshot 44.39 shows text being set in the editor.. tahoma, 16pt, blue
Screenshot 44.57 shows what appears on the screen... which is not 2 lines of text at 16 tahoma
Screenshot 40.44 shows the tahoma selection
Screenshot 40.15 shows another variant when both bits of text are selected with 16pt tahoma
These are samples from the site direct!!!!
Have now had a number of attempts at trying to change just TWO WORDS! What is so difficult about that??????? This is wasting so much of my time!!!!!

<p style="text-align: left;"><span style="line-height: normal; font-size: 16px;"><span style="font-size: 16px;"><a href="/Home.aspx"><span style="font-family: tahoma; font-size: 16px; color: #548dd4;">Home</span></a><br />
</span><span style="font-family: tahoma;"><br />
<span style="color: #548dd4;">Accredited</span></span></span></p>
<table align="center" style="width: 100%;">
<thead>
Both words were selected Tahoma 16
Screenshot 06.40 shows what appears in the editor
Screenshot 06.55 shows what is appearing on the page.
These are again from the site direct
Please, note that version 5.0 or later of DNN uses the Professional provider of RadEditor, which is implementation of the DNN developers and it is not supported by Telerik. Our suggestion is to post your question in the DNN forums and contact the support of DNN for help.
In addition, by default RadEditor copies the CSS registered on the page in order to apply the same decoration and it is possible some external CSS to overwrite some of the values and change the appearance of the content. To disable this behavior you need to set CssFiles property of RadEditor, for example you can set it to point to a dummy CSS files without any CSS. Could you please try using the above mentioned property to register an empty (dummy) file and see if the problems still exists?
