As you can see in the image attached even with some of the frames using the New Window depth on some of the children it still does not quite behave as it should when the dropdown overlaps other GUI elements.

It is setting the values but the GUI is not displaying them after they change. At least from my testing it seems like the issue lies somewhere there.

Example addon to test the issue: https://gist.github.com/Calebzor/b63e749e9ad912fc094e

Try and change anything with dropdowns, the display won't update to it.

As you can test in the following example addon the tree group type does not refresh after the initial select.

On the left side of the config window just click all of the groups once and you'll see that once you've clicked them all, you can no longer switch away.

If I put GeminiConfig inside a foldier of my addon, say: Libs, then GeminiConfigRegistry will fail to load with the following error:

...Addons\EsperH\Libs/GeminiConfig/GeminiConfig-1.0.lua:21: cannot open C:\Users\Calebzor\AppData\Roaming\NCSOFT\WildStar\Addons\EsperH\GeminiConfigRegistry-1.0\GeminiConfigRegistry-1.0.lua: Result too large

I have this code:

    self.myOptionsTable = {
        type = "group",
        args = {
            locked = {
                name = "Lock/Unlock",
                type = "toggle",
                get = function(info) return self.db.profile[info[1]] end,
                set = function(info, v) self.db.profile[info[1]] = v; Print(tostring(v)) end,
            },
        }
    }

And by the looks of it set is not called when you untoggle the button.

You can verify in the following example addon ( https://docs.google.com/file/d/0B5Hgmr1RAr3NcEZFVGdVUG5kaTg/edit ) that the two first groups have same amount of headers in them. When you scroll to the bottom of the initial one ( aka Group 1 when opening the config window ) you can see all, but if you switch to "Group 2" and scroll to the bottom, the last widget won't be displayed. Now if you go back to "Group 1" it will no longer have the bottom widget displayed either.

A workaround this bug is to always have an empty description widget at the bottom of every group.
