What is the event script to write to a property on another window? I cannot find how to do this.

Generally you don’t want to write to another window directly because it might not be open. I recommend using a client tag on both screens. It’s easier and much easier to figure out in a couple months when you’ve forgotten how these screens work. Just bind/write to it on both screens.

If you really need to write to another window, you have to get the window handle with system.gui.getWindow(“WinName”).getRootContainer()… to find a property on the screen.
