Language-problems in OS X 10.3.6

[PaaC]

Dear mac-users

I purchased an iBook for about two weeks ago from Apple store (Swedish version)
I got it on 11th nov. and im really pleased with it!
Now to my problem:
My OS X is in swedish, but suddenly the names on all apps changed to english. Even the folders that was pre-installed (like "movies", "music" etc.) changed to english.
Not a big problem, but its a bit irritating.
I know I could just rename it all, but it should take a while.
So, does anyone know how it could just change, and how could I change it back?
Thanks//Patrik

Check if: System Preferences -> International is correct.
If you would like everything on Swedish, Swedish should be on the top.
You also have to logout and in again to make things change (otherwise it's just all newly started programs that will be in Swedish).

Hope that helps.

I checked if swedish was at the top of the list, and it was, so I logged out, but when I logged in again EVERTHING was in default settings. The dock, wallpaper, etc.I think I'm going crazy!
One more thing, how do you make a picture on a folder?
Thanks for you're help... think I just have some bad luck.
