I know one can have a big file containing customization for all the X apps, but I'd like to be able to modify the app-defaults/xxx file for the xxx app. without having it being overwritten when a new release of xxx is available? Is this a bad idea? YA. -- Yves Arrouye Email: Yves.Arrouye@marin.fdn.fr 7, avenue Leon Bollee Web: http://www.fdn.fr/~yarrouye/ 75013 Paris Work: +33 45 95 64 59 France Home: +33 53 61 09 55
