The Channels window spawns automatically with the use of /list, you can close it using /window -c "Channels List" in your raw command.. i.e. raw 321:*:{ window -c "Channels List" } raw 322:*:{ echo -s -> $1- | window -c "Channels List" } raw 323:*:{ window -c "Channels List" }
The downside is that you may actually see the window open and close.
