Controlclick doesn't click

[lolipop]

Anyone have any idea why the first instance of the controlclick function doesn't work? Below is my code. I can see that the controlclick does change the focus to the Button2(Save button) but it doesn't click at it.

Btw, I have tried all the following below as well but it still doesn't work.

ControlClick("File Download - Security Warning", "", "[CLASS:Button; INSTANCE:2]")

ControlClick("File Download - Security Warning", "", "[iD:4427]")

ControlClick("File Download - Security Warning", "", "[CLASS:Button; INSTANCE:2]","left",1)

#include <IE.au3>

Global $SequenceNumber32bit

GetFileName()
Download32bit()

Exit

Func GetFileName()
    Local $oIE = _IECreate("http://www.symantec.com/security_response/definitions/download/detail.jsp?gid=savce", 0, 0)
    _IELinkClickByText($oIE, "Start Surfing")
    Local $sString = _IEBodyReadHTML($oIE)

    Local $iPosSeqStart = StringInStr($sString, 'http://definitions.symantec.com/defs/')
    Local $iPosSeqEnd = StringInStr($sString, '">', 0, 1, $iPosSeqStart)
    $SequenceNumber32bit = (StringMid($sString, $iPosSeqStart + 37, $iPosSeqEnd - $iPosSeqStart - 37))
    _IEQuit($oIE)
EndFunc   ;==>GetFileName

Func Download32bit()
ShellExecute(@ProgramFilesDir & "\Internet Explorer\iexplore.exe", "http://definitions.symantec.com/defs/" & $SequenceNumber32bit, "", "", @SW_HIDE)

WinWait("File Download - Security Warning")
WinActivate("File Download - Security Warning")
ControlClick("File Download - Security Warning", "", "Button2") ; this clicks the default "save" button on the first dialog

WinWait("Save As") ; Wait for the "Save As" box to pop up
WinActivate("Save As")
Sleep(100)
ControlSetText("Save As","","Edit1", @ScriptDir & "\" & $SequenceNumber32bit) ; reset the name of the file to the original value.
Sleep(100)
ControlClick("Save As","","Button1")
EndFunc

There would not be much point to Security Warnings if they could easily bypassed by an application.
