OS X doesn't display Finder's default icons in the right language
I bought a 15" PowerBook G4 (first time switcher, yay) while visiting States earlier this summer and to my joy I found out that I can change OS X's language to my native language, Finnish. Could've never happened with WinXP... anyway, everything worked well until one day I noticed that instead of Finnish, Finder displays English text next to the standard icons (Network, Macintosh HD, Desktop, Applications, Documents, Movies etc.). Otherwise everything else is still in Finnish, including Finder's menu. Interestingly when I access my HD via Open/Save dialogs, all those standard icons have Finnish text. I've tried changing language to English and then back to Finnish, without any success. Even though this is not a critical bug, it's highly annoying. I love my PowerBook and OS X and I want it be perfect. What could've caused this and is there an easy way to get Finnish text back (or ANY other language for that matter)? The OS is Panther.
