Money 2004 Deluxe

I cannot rename the Canadian Dollar currency to "$".

To rename a currency go to <Tools> <Options> <Currencies> tab, select the
currency then <Rename>.

I can change it anything but "$" but when I change it to "$" Money changes
it back to "CA$". I'm sure it has something to do with US $s so I changed
the symbol of US Dollar to "US$". This didn't help, I still cannot change
the Canadian dollar symbol.

This works in Money 2003! Why not 2004? Will someone try it in 2005 for me
please?

Thanks in advance.
