first, remove the middle line with the = key in it; that's a default from Sorn's script that only he uses; = is his "Assist" macro hotkey, he wrote the script so it would assist on every press, you don't need it lol

Second, if that doesn't fix it, try the ofllowing:
[code:1]#IfWinActive, World of Warcraft
~`::
ControlSend,,{` down}{` up}, ahk_id %idMain%
ControlSend,,{` down}{` up}, ahk_id %idClone%
return[/code:1]
