Salut Stief, if he had port 6348, maybe he was running two instances of LW, which is possible under windows (this happened to EllisD). Anyway it is weird and LW shouldn't allow two UP connections of the same ip and port.
Here is another thing weird, an UP connected for more than two hours but it didn't even sent a QRP??? Has you can note on the shot it isn't a 0.6 normal peer either....
