If I package a development build and start it up with Switchboard (with SwitchboardListener running on all nodes), the nodes will start up and sync up.
If I use the same package development build and start it up via command line using what Switchboard would have sent, each node stays dark, waiting on the other nodes to connect. When I start them up, they will connect and start up, but I can tell the mouse movement isn’t syncing across them (starting via Switchboard, move mouse, all nodes move, start via command line individually, move mouse, only the node’s screens will move).
I am going to perform some more testing to see what the heck is going on.
