My user has a region of cells 900 rows by 40 columns with text and some of
the cells are shaded pink. When she copies data to another file, it looses
the fill color.

I tested the copy with a two cell range and that copied in the color. She
tried just one column of the 40 she had, still selected all 900 rows and that
copied over the color

She has Excel 2003 - I need to check the SP level. We normally run SP3
