Hi Niko (and all readers :-)
Some news : this morning, Hamachi didn't connect just after Windows starting. I'm sure of that. And more than 1 hour later, it's the same. Hamachi doesn't connect automaticaly.
A right-clic on the name of the server, then "Connect", and Hamichi is connected.
If this informations can help you to solve my problem with Hamachi :-)
Best.
Stéphane
