Hi, I changed your sample just to add more print info, and it is working here. See attached. I suspect this could be an old bug already fixed in previous versions. IUP 3.11.2 has more than 4 years now...
Here is the output:
D:\tecgraf\iup\bin\Win64\Lua51>lua5.1 \Downloads\close_show.lua
SHOW_CB state=0
CLOSE_CB
SHOW_CB state=4
destroy
Best,
Scuri
