I found in the MD onScreen Orbiter log those messages:
10 08/19/06 17:28:56.850 Another device with IP REPLACE 192.168.80.2 connected as device: 212
== PromptUser( An Orbiter with the same device id was started on 192.168.80.2.
This Orbiter will be closed., 10, 0xb5af79b0 );
I suspect the problem related with this. Can somebody help me, please, resolve this?
P.S. I don't have two Orbiters connected to the one room (I check it on the pluto admin Orbiter page)
