Losing all formatting in Excel 2007 files

[stumped Al]

I have Office 2007 running on an XP desktop and a Windows 7 laptop. I work
on an Excel .xlsx file on my desktop but when I open it on my laptop all of
the formatting is lost.

I have had this exact same problem except vista to xp. I wouldn't lose all
of the formatting, but some words would would be on different lines. Other
things I have noticed is that my Office 2007 on Vista doesn't always have the
same fonts as on my Office 2007 XP. I think the formatting issue is more of a
compatibility issue.
