No, the file size and modified dont change. I tried Excel 2003 files under
Excel 2003 and Excel 2007, and the issue affects both. How is it that FC is
picking up a difference yet the file size and last modified date remained
unchanged?

If the MD5 hashes aren't matching up, I would check the file size and
last modified date instead.

I have some old backups of Excel 2003 documents and would like to verify
current copies against them! Therefore i am using the MD5 hashes for
comparing. But obviously this is failing because just opening and closing a
file causes the MD5 to change making the whole exercise useless! I do not
have any issues with any other type of Office 2003 documents.
