Nostalrius Begins - Quality wow vanilla realm (1.12)

I really want to get rid of the mouseover tooltip (bottom right corner). That's why I tried both "Move Anything" and "Tiny Tooltip", but neither of them worked for me. When I enable the option to hide the tooltip, the game ignores that and continues to show the tooltip. And when I move the tooltip outside of my screen limits, the game puts it back on my screen.

Does anybody have advice? Would really appreciate it.
