Cell Fill Color and text color - changes for recipient
 

I just learned that a worksheet I sent to someone - where cell F11 contained
black text and light grey fill (as displayed on MY laptop) was recevied with
black text on black cell fill.

Another cell (as displayed on my machine) had blue text on no fill, but was
viewed as light green text on no fill. Just to eliminate the obvious, I sent
the same worksheet to another recipient and the changed color appearance was
the same for both recipients, leadign me to think the problem originates with
me.......

I'm using Windows XP Professional and MS Office Excel 2003. Any clues as to
what the problem is - as well as how to fix it?

Thanks.
