Hi there!
I'M not on my computer right now, but if I understood you right, you want for the player to be able to manually hide the controls while the message is opening?
If it is that, I can see what I can do. But I believe the main problem is how did you disable the mouse/touch interaction on ROG Maker. Because I believe there is safe ways for doing that, without remove the feature of the player progress the messages by pressing on the message window.
Can you tell me more about that?
