Sorry, this may be somewhat off topic:

Temporary I have to use a notebook that is not mine.

On my notebook, when I format a cell in Excel to the currency "Spanish
(Costa Rica)" appears the correct symbol that is somewhat similar to a
C with a double slash. I use Win XP SP2 and Excel 2002.

On the other Notebook it is also Win XP SP2, but Excel 2000. When I
try to format the same, in the format menu I see the correct symbol on
screen, but on the spreadsheet I get only a rectangle on the screen as
well as on the printed sheet. On former formatted spreadsheets I see
the same rectangle for the currency instead of the symbol. -- In the
country settings for the computer I can see the correct symbol for the
Costa Rican currency - on the screen.

Where is that symbol set for currencies stored and why doesn't Excel
use it correctly? (Excel doesn't use the symbol for the Mongolian
currency neither - but that concerns me much less ;-) )

Thanks for your patience and help!
