while in advanced lon manager, i get the channels and nodes to show, however the light bulbs are not lit. everything is working i was just doing some experimenting, and in the book it says the bulbs should be lit. if i select find nodes, a node will appear, and it will be lit. i know my lon talk card is good, i guess my question is why are my bulbs not lit. are the bulbs supposed to be lit. if i choose replace node, and then upload the lonconfig file, then go back to advanced lon manager, then the bulb will be lit next to the node i replaced. i don't have to worry about screwing up the system, as this is a simulator i am playing with. any ideas
