autoit controlCLick() function problem

Hi

i don't know if anyone here can help me with the problem i am confronted with.

im trying to use the ControlClick function in an autoit script but it does not work.I have no problem with the ControlSend function tho.

i tried different things to solve the problem like changing resolution to : custom fullscreen, switching up ControlClick parameters :

ControlClick("Vindictus", "","[CLASS:Valve001]", "left",1,109,932)
ControlClick("Vindictus", "","", "left",1,109,932)
ControlClick($hWnd, "","[CLASS:Valve001]", "left",1,109,932) //$hWnd being the handler to vindictus
ControlClick($hWnd, "","", "left",1,109,932) //$hWnd being the handler to vindictus

I also tried changing the mousecoordMode but nothing worked so far.

Does the program block click input while not active ?

Thanks in advance for answers.

ps. sorry if i am unclear , i'm not used to writing in english.
