Yesterday I coloured / shaded cells in a worksheet and closed the file. When
I reopened it today, I could not see any of the colouring / shading. I know
that the colouring / shading is there because, whan I copy and paste the
worksheet into Word, there they are.

Can anybody please help as to what's happened and what I should do to get
the colouring / shading to be visible again in my worksheet?
