salut j'ai remarqué aussi cela et j'ai ecrit au staff d'omniweb voici le message qu'ils m ont envoyé :
OmniWeb used to just hand files it downloaded off to the finder to send to the default application for dealing with that type of file. Problem is, starting with Mac OS 10.1, the finder will happily send a .jar file off to Apple Applet launcher, and execute the file with root priviledges. Not good, from a security standpoint.
So we changed our behavior; We're still trying to decide what the best thing to do with files we download at this point, so if you have any suggestions, let us know about what you'd like to see happen.
autrement dit si j'ai bien compris ils ont supprimé cette fonction car les installations se s'effectuaient en root
voila
