Update: tcp-tagging forwarding
The Display Cue Image box forwards to TCP Tagging any stimulation received.
If the box is in a scenario with another box also forwarding to TCP Tagging (e.g. Sound Player), stimulations end up being duplicated as they are sent by both boxes to the the A.S. via TCP Tagging.
Forwarding stimulations on TCP Tagging should be made optional for theses boxes. A difference could be made for stimulation passing through and those which are actually used by the box.
