I found a bug. The "advisor" slider does not work. And I found a way to fix the bug - can you replace lines:

containerWindowType = {
name = "voice_types"
position = { x = 290 y = 50 }
size = { width = 250 height = 490 }
clipping = yes

gridBoxType = {
name = "gridbox"
position = { x = 0 y = 0 }
size = { width = 250 height = 490 }
slotSize = { width = 250 height = 38 }
max_slots_horizontal = 1
format = "UPPER_LEFT"
}
}

with that lines in "government_view.gui"?

containerWindowType = {
name = "voice_types"
position = { x = 290 y = 50 }
size = { width = 250 height = 490 }
verticalScrollBar = "right_vertical_slider"
margin = { top = 2 bottom = 2 }

backGround = {
name = "bg"
position = { x = 0 y = 0 }
spriteType = "GFX_tiles_dark_area_cut_8"
}

gridBoxType = {
name = "gridbox"
position = { x = 0 y = 0 }
size = { width = 250 height = 490 }
slotSize = { width = 250 height = 38 }
max_slots_horizontal = 1
format = "UPPER_LEFT"
}
}

That will helps a lot for those, who play with warious custom advisors mods.
