Please look again at your export options. I just tested the export for 2 options that Crystal XI offered me: 1) Microsoft Word (rtf); and 2) Microsoft Word - Editable (rtf). While both exports allowed me to make changes and seemed to maintain my formatting, option 2 above (editable) allowed me to edit the document just like any Word document.
The export into the rtf that did not specify editable entered all of the data into separate cells or tables. While I could edit any particular cell, I do not have the freedom to move a cell around or edit freely as in Word.
