Hi Rilgamon.
I have correct the iussues you pointed out in this way:
Lua Code:
local ADDON = ...
-- [ ... ]
local options = CreateFrame("Frame", ADDON .. "options", InterfaceOptionsFramePanelContainer)
-- [ ... ]
local button1 = CreateFrame("button", ADDON .. "button1", options, "UIPanelButtonTemplate")
-- [ ... ]
It should be ok now even if I don't think they can solve the iussue in the first post.
Btw thanks so much for your reply. It is really appreciated.
