Use a script call on the event:
this.setWaitMode('message');
so that it when the text box pops, it is handled like a normal message and other events won't trigger until it closes. See if that works for you
Sure, you're right, but I thought it will be implemented inside a plugin after all, don't get me wrong this is great plugin and after few minutes with cup of coffee and analyzing it I feel bad for rating it just 4/5. It deserves 5/5. I'm really glad I found you on Lunatic Server on discord server. Good luck with developing this plugin and keep up with good work. When I will have a day off I'll check it with my plugin that does exactly the same, but texts and params such as window background, position and face index are stored and read from csv fle. If it will turn out your plugin is faster, I'll switch to yours.
