I have a Promethean (Nickel) Panel and I have been unable to get “touch” to work on the panel while is extended view. I have a Dell Desktop (Optiplex 7010) – Windows 10 – that it is connected to. I can set to extended view and slide windows over, but the touch will not work at all. Is there a setting that needs to be made? If so, can someone share or make suggestions? THANKS!
