I have Excel 2007 but save a certain spreadsheet in Excel 2003. I use
Compatibility Mode to edit document. I saved my document and all my
formatting was gone (nothing highlighted, all borders were gone, alignments
were messed up, etc...). Now anytime I change any of the formatting back to
the way it was and click save it reverts back to the unformatted form.

Very Frustrated,
