I'm trying to enter the path to my picture folder in the desktop integration tab, but winecfg refuses to accept the Spanish word for it, which is "Imágenes." Both typing the path manually and using the browse dialog work, until "Apply" or "Accept" are clicked on, when the previous path is restored. Any path not containing an accented letter seems to work.
What's your locale?
