Thank you for responding.
Perhaps the best approach (since I am not allowed to upload a Word docx) is to provide the direct link to the client website showing the news release that is producing this failure.
Please go to this page: http://www.kivalliqenergy.com/news/index.php?&content_id=87
Then copy the entire news release into a Word docx.
When I did this and then attempt to create a new page - I can paste from the created Word document into a content block and it will preview correctly.
However, when I attempt to create a news item and follow the same process (with the exception that the news release title line is pasted into the Title line of the news item content field) the table balloons up to may times its original size.
If I can be allowed to send the Word docx to you this will allow you to skip the first step.
Incidentally, the client usually creates these news releases in a Word docx initially.
