Formatting in Excel 2007

[Griffen]

I've upgraded to Excel 2007, and now when I open some 2003 files, I lose all
formating, (colors, borders, numbers, etc) Does anyone know if the service
pack will fix this problem or is there another solution. This doesn't happen
on all 2003 files, not sure why??

Hey...

I'm having the same issue. When i save XLS file with Excel 2007, it
randomly removes the cell formating. Formula's typically survive. The
really wierd thing is that this started recently. I have Excel 2007 since
feb '08.

any help would be extremely appreciated!!
