When I stop the train and use Ctrl/M to switch to manual control of signals and switches this works fine for a while. However as I roll along for a while and come up to another switch and hit G I get the alert that the switch is locked. Then I have to stop the train and do the Ctrl/M again. It seems that after running a short while the sim defaults to dispatcher control. Is this something I am doing? Actually I have not done anything except switch the main a few times or perhaps only once.
