Need help detecting desktop lock

[rcmaehl 36]

Currently I'm using

Func _GetDesktopLock()
    Local $fIsLocked = False
    Local Const $hDesktop = _WinAPI_OpenDesktop('Default', $DESKTOP_SWITCHDESKTOP)
    If @error = 0 Then
        $fIsLocked = Not _WinAPI_SwitchDesktop($hDesktop)
        _WinAPI_CloseDesktop($hDesktop)
    EndIf
    Return $fIsLocked
EndFunc   ;==>_GetDesktopLock

that I found from @guinness in another thread, However this seems to have a issue whenever UAC pops up as it'll return true. Is there some way to fix this?
