4085	__GUICtrl_IsWow64Process($hWnd) issue	Nine		"If the $hWnd does not exist (because the window has not appeared yet for example), the function returns @autoitpid which can result in faulty (buggy) return.

I would suggest to return an error instead.  So changing :
{{{
If Not $iPID Then $iPID = @AutoItPID
}}}
to :
{{{
If Not $iPID Then Return SetError(1)
}}}
would make the function more robust."	Bug	closed		AutoIt	3.3.18.0	None	No Bug
