Bold Works, None Nope.

Why ControlClick? thats why i want use a Mouse Click to improve my Control Skill , just Control Send would be so easy to me, I'm always looking for hardest way so.

Opt('WinTitleMatchMode','2')
$Title = 'Kalkulator'
$process = WinGetHandle(WinGetTitle($Title))
ControlSend($process,'','',"{2}")
ControlSend($process,'','',"{+}")
ControlSend($process,'','',"{2}")
ControlClick($process,'','',"left",1,200,250)
