I'm using Excel 2003 and there I have inherited a spreadsheet where the
background colour on the worksheets with content are grey for the entire
worksheet. I have tried all obvious routes to remove it, fill colour,
autoformat, sheet background option, any macros that might be causing it but
it appears none of these are the case. The fill colour won't change. I', sure
this is explaining the very large file size. Any help appreciated.
