Hey Lokasenna,

I found a bug when closing out a "Window" class. When closing a window it calls

function GUI.Window:showlayers()
    
    -- Set the layer visibility back to where it was
    for i = 1, GUI.z_max do
        GUI.elms_hide[i] = self.elms_hide[i]
    end
    
    -- Hide the window and its child layers
    GUI.elms_hide[self.z] = true
    for k, v in pairs(self.z_set) do
        GUI.elms_hide[v] = true
    end
    
end

Here was the behavior I saw:



Redrawing the previously hidden layers worked after I reset the hidden elements table:

    for i = 1, GUI.z_max do
        GUI.elms_hide = {}
        GUI.elms_hide[i] = self.elms_hide[i]
    end

Probably should submit a pull request on your github sorry!
