Hi,
yes you can add it to the RefAllHome() function, I would put GoCenter() just before the message box.
The advantage of having the GoCenter function code in the screen load script is that it is visible
throughout the Mach GUI and is therefore perfectly permissable to call it from another function, in this case
RefAllHome(). Not sure how the coroutine part would affect it. Note that the screen button will work per normal,
there is no need to disable it.
Try it and see.
