Keyboard Layout

Hi, my keyboard layout is behaving a little strange. I use English(US) as my default layout but each time i boot the system it loads a different layout. I think it is German or something like that because it has the -umlauds if i say it correctly-. Anyway, if i run yast and select keyboard layout, i see that English(US) is checked and if i press Accept then my layout is ok. What can cause this because it wasn't always like this. Is there a config file? Thanks!
