Tickets utilizes Growl to notify the user when certain events occur. Events include user generated updates (save or send changes) and notifications when cases are updated from the server
Growl notifications may be clicked on. Clicking on a Growl notification will bring up the referenced case in Tickets.app
Notifications will not be generated when Tickets.app is the front most application.
Notifications will not be generated for incoming cases if they are marked as spam.
