A problem about wow auto-login script

Hi all,

I've written a script for auto login wow, as the following shows:

#Include <Array.au3>
#Include <WinAPIEx.au3>
Local $PID = Run("E:\wow\wow.exe", "")
Sleep(8000);25 seconds is a bit much...
Local $Result = _WinAPI_EnumProcessWindows($PID)
Local $hWnd = 0
If @error Then
MsgBox(4096, "Error", "Cannot find process Window")
Exit 1
EndIf
If IsArray($Result) Then
$hWnd = $Result[1][0]
Else
$hWnd = $Result
EndIf
Sleep(100)
Local $rect = WinGetClientSize($hWnd)
If $rect[0] = 0 or $rect[1] = 0 Then
exit 1
EndIf
Local $newx = $rect[0] * 0.5
Local $newy = $rect[1] * 0.525
WinActivate($hWnd)
Opt("MouseCoordMode", 2)
$click = ControlClick($hWnd, "", 0, "left", 4, $newx, $newy)
MsgBox(4096,"click", $click)
Sleep(100)
ControlSend($hWnd, "", "", "test");Sends it to the game, wether your in game or not. Account name.
Sleep(100)
ControlSend($hWnd, "", "", "{TAB}");Moves down to the password field.
Sleep(100)
ControlSend($hWnd, "", "", "password");Sends it to the game, wether your in game or not.
Sleep(100)
ControlSend($hWnd, "", "", "{ENTER}");Moves down to the password field.
Sleep(100)

Firstly, I want one more click since it's more reliable because the focus isn't always on account name

Second, I use ControlClick instead of MouseClick for it doesn't move mouse visibly.

Result: it just doesn't work. however MouseClick can work

Please give me some suggestions

Thanks
