    EndIf
EndFunc ;==>Calc

Func AutoItHelp()
    If FileExists(@ProgramFilesDir & "\AutoIt3\AutoIt.chm") Then
        ShellExecute(@ProgramFilesDir & "\AutoIt3\AutoIt.chm")
    ElseIf FileExists(@HomeDrive & "\Program Files (x86)\AutoIt3\AutoIt.chm") Then

    EndIf
EndFunc ;==>MainPlayList

Func NewlyAddedPlayList()
    If ProcessExists("iTunes.exe") Then
        For $TempPlaylist In $oiTunes.LibrarySource.Playlists
            If $TempPlaylist.Name = "Newly Added" Then
                $TempPlaylist.PlayFirstTrack
            EndIf

    EndIf
EndFunc ;==>NewlyAddedPlayList

and I noticed something eairler when testing something. If I run a game as administrator the itunes hotkeys will not work while the game is the current focus. I forgot to test my other hotkeys to see if its an itunes only thing. Also I did notice this once when I was installing a program as administrator. Anybody have any idea why this would happen?
