Hello again, I succeeded in displaying Growl notifications: - I launch the script if the designated user is logged in - In the script, I call Growl to send a notification if Growl is started. If the designated user is logged in with Growl enabled, the notification is visible If the designated user isn't logged in, but another user is, the script isn't called, so no notification is sent. So far, so good, but I have a last problem... If two users are logged in, the designated one and another user, _and_ the actual working user (the one which is using the keyboard and screen, I'll tell him the 'active' user, because I don't know how it should be called) isn't the designated user, my software recognize that the designated user is logged in, and tries to send the appleScript. This ends on an error, Growl returns this message: "_RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() is NULL." This result surprised me, because I tried before, and growl is able to send notifications for one user, when it isn't the active user and 2 or more users are connected (I tried myself, launching regularly notifications, and switching back and forth to another user.) I don't think I can discover the name of the active user, I don't see anything in the utmpx database to help me... Can anyone think of a way to handle this error, or to avoid it? (I forgot to explain that after the error, the appleScript take about 100% time of one processor, and it has to be killed with activity monitor, because force quit in Apple menu don't work for it!!!)
