OpenOffice Calc with "decimal separator key"

I need to use OpenOffice Calc a LOT!!! As an accountant I really have to !!!
I use Fedora Core 6 with American English language by default.
Since I live in Portugal I define OpenOffice to use the Portuguese defaults like the "decimal separator key" (the key with the decimal point on the numeric keypad, next to the "zero" and "Enter").
Normally pressing that key in Portugal it produces a "," (comma). However, the OpenOffice Calc in FC6 produces a "." (decimal point). In Ubuntu 6.10 the key works as expected giving me a ",".

Can anyone give me some help on this subject?

I enclose an image so you can see what I've done (that's the same as I've done in Ubuntu 6.10).

Thank you.

Never mind my question, the latest update for OpenOffice solved the problem.
