Autoit3 Hotkey in KO- help : KO Discussion

hey, i'm making a macro in AutoIt3.
i made a hotkey, to toggle auto attack on/off:

HotKeySet ( "{" & $StartStopAttackKey & "}", "AutoAttack" )

now, while in KO, the key doesnt response.
if i do alt+tab, it works.

anyone have any idea how to set hotkeys to work on KO?

btw, if anyone can help me with memory reading, pm me.
