I have the latest available NoMachine build (4.0.369) installed on an OSX 10.6.8 box.
When the machine is booted, I get the black icon in the menubar indicating that the NX server is running. I open the server status window, stop the server, and click “No” when asked if the service should automatically restart upon rebooting. I then exit the server and the black icon disappears.
However, when I restart the machine, the server automatically restarts (and the black icon shows up again in the menu bar).
Am I doing something wrong, or is this a bug?
