Here is the scenario



I create a document with specific formatting in it, columns, margains, etc in office 2010. My assistant then makes some edits on it using office 2007 and saves the file. I open the file back up in office 2010 and my margains are all out of whack, some cases the columns are as well. Does anyone know of a proper work around for this? It isn't practical to have to do this on every document I receive back.

Thanks in advance

UPDATE:
Now it doesn't matter, I create a new document, format it (margains, columns, etc...) all looks good, save it, open it back up and it's all out of whack. I attempted to remediate the issue following the suggestions here: http://support.microsoft.com/kb/918429 but none worked.
