colour changing within network

[david wiggins]

Hi,

i have made a spreadsheet and have filled certain cells with particular
colours, but when it passes through our network, the colours change. what's
more is that in the colour information, this table has been rearranged! (i.e
if i select a colour 2 from the left at the top of the colour sheet, on
another pc connected via the network, the colour two from the left at the top
is a different colour!)

oh and ps. i am using vista whereas the other pcs use xp. could this be part
of the problem?

any views?

thanks
