Help! I just installed IDE 2.1.1 and it takes a long time to load. Windows Firewall blocked a file called mdsn-defender that had downloaded with the IDE. Then I found that the monitor would not connect to a Mega 2560 board although I had selected the type of board and the port it was connected to. It just failed to find the connection and timed out. No idea where to go from here, so am re-installling 1.8.19.
If any one has any ideas please let me know.
