Post 42 => Go to tools- options- table- multi-tabling- unclick "enable active table popup"

If we play some tables in stack an disable this option the table that requires action dont go front, so this option isnt useful.

I tried to disable Auto z order and force HUD on top and magically the problem is solved. I said magically because after that I enable again Auto z order and force HUD on top and the problem doesnt happens, I dont understand but problem is finished.
