Changing appearance of NPC's speech text

[Barn Owl]

Hi all, I am a huge fan of AGS and all you folks. It's a beautiful thing.

I am making a game, yet there is one issue I am running into, which is the fact that I'm kind of an idiot. I know this is in the manual, but I'm having a tough time finding it there...

I am using the SierraWithBackground text presentation which is great for the main character. I like the way the text in the box looks. However, I dislike the no-box text when non player characters are speaking.

Could anyone be so kind as to assist this poor manual-challenged fool as to how to add a box to the text presented when NPCs are speaking?

Thank you, brilliant adventurers.

NPCs are supposed to use same speech style as player character.
I know of 2 reasons why the may be displaying simple text instead:
1. You did not assign speech views to them.
2. They are in different room.

Thank you! That was helpful!
