setting of language and formatting of numbers

[Poldi Winkler]

Hello,
I'd like to get your help again.
I am using gnucash 1.4.8 and KDE2 with SuSE 7.0. My language is (was) German 
and the formatting of numbers is (was) 1.234,56.
After I have played with gnome and afterstep and fvwm2 in gnucash my language 
is English and the format is 1,234.56 (the other programs are not changed).
The language in kde is German and also the format is OK. 
Therefor I believe I have changed the settings in gnome. Does anybody know 
where I can change back my setting?
Thanks in advance.
Regards Poldi
