Is there any way to close the spontious dialogue boxes that popup when the Bethesda forces their quest/mission upon the player? Bryan Wilks [Those! quest] popped up out of nowhere. After reading all the options, I found that I can't close the box. There is no exit button nor close option in menu control setup, I pushed every button on the keyboard to no avail. I have wander mod, they do have a 'I got to go' option. I don't dare start any quest if this company did not put vanilla exit dialogue options.

hit tilde (~) and type 'closeallmenus'

I will try this. Is it a developement bug/glitch?

I don't know about that specific quest, but sometimes mods can cause the goodbye dialogue choice to not be there.
