Restricted Access on Turn Counters

I’ve made a turn counter button that is attached to the general overhead area where you have undo, step forward, etc. However when an observer checks out the game, they can press the button and alter the turn. Is there a way to restrict access to the button or the function itself?

Thanks in advance for the help for me figuring this one out.

I tried, but I don’t think there is a way. But if you find out one, please post it here

Ha! Will do. At least I’m not the only one who had trouble with this. I thought of making it a private window, but that just seems excessive to stop tampering from observers.

Is that even possible (to make it a private window)? Didn’t find how.
