When running Rail master V1.74 on my laptop Lenovo 15in on the main screen top right corner there is 3 items that light up
1 I think its the world I imagine the internet
2 is the Elite Controller
3 is loco
No 1 does not light up so if I want to deactivate rail master it will not connect to the server error 12029
No 2 Lights up
No 3 Inactive
Hope this helps a bit better.
