hi~ GetKeyState("Alt", "T")  cant return correctly

#Include %A_ScriptDir%
#Include IbInputSimulator.ahk
IbSendInit("AnyDriver",1)

$q::
    else if GetKeyState("Alt", "T") 
    {
        Send, !q 
    }
    else
    {
        Send, 1  
    }
return

I tested with this code.... alt q only be used few times...some times when i press alt and q , and it still send 1...

no idea why

if i use GetKeyState("Alt", "P") , it goes more worse
