I suspect that both are working as designed. You running 2 programs that are trying to use a single-user interface. This is a conflict that probably cannot be fixed without a major overhaul of the interface and programs that use it.
The loss of the message is undoubtedly due to NETSTAT discarding it as an unknown message/command.
