Launch ClarisWorks (preferably in English, so you can see the two different menus in different languages), create a document, save it. Go to the Finder, click on the document, and under the File menu, choose Open. You will see that the word "Fichier" overlaps the word "Edit" in the English version and "Edit." in the French.
When working with the French version, it seems (incorrectly) that the "Fichier" is the application menu, not the Finder's; therefore, one is given the impression that the application menu has been altered.
This is a known bug.
