Resize Dialogue Box

Hello :D

So, I have being trying to figure out and customize my UI and I've got problem to customize the "dialogue" box when talk with NPC.

I wanna resize it so its easier to read. I already know I can change scale for the UI on the Menu, but what I need is a effective way to resize only the dialogue box.

The only way I find to do this is "right click" over it, go to scale window and choose the size there.

It works well, but for some reason, the game don't save this settings, so everytime I close the game, I need to change this again when I'm back.

And there is another problem, the game recognize "right click" on the mouse as a "next" click on dialogue box, so, when I right click, it advance to next text, so, everytime I open the game, I need to find a NPC with more then 3 dialogue box to be able to access properly that menu Lololol.

Anyway...

Someone have some idea to help here? :D

Can you go into the UI Config tool and change it from there? The scaling should be saved if you click save in there.
