Hello, we just upgraded our OTRS from 2.2.4 to 2.4.1. It works fine so far - except we miss the red alert "New message!" in the black subject bar for unseen messages in new and/or existing tickets. We rely on this feature to scan as an agent e.g. "Watched Tickets" for news quickly. I broke down the problem as follows: - the former Kernel/Modules/AgentTicketMailbox.pm is omitted in the latest version of OTRS completely - in revision 1.21 the check for "if ( !$Flag{seen} ) ..." is gone - I suppose this is the source for the feature http://source.otrs.org/viewvc.cgi/otrs/Kernel/Modules/AgentTicketMailbox.pm?... Questions: 1. How can we re-activate this nice feature? (maybe we have to patch our OTRS - a pointer to the new according source code is welcome) 2. How is the recommended way in latest OTRS-versions to identify tickets with new messages quickly? Regards, Christian Meier E-Learning-Support TU Dresden
