Try something like the following:
[/code]function OnEvent_ChatWndCreated(ChatWnd)
{
  if (Messenger.MyStatus == 4)
  {
    MsgPlus.PlaySound("Notify.mp3")
  }
}[/code]
This script will give you a notification via sound of someone starting a new chat with you (though it will also do it when you open the chat window, sorry but it is a limitation).  Also it doesn't use the proper WLM sound, it just uses a notify sound that MP!L has (though you can just change the file).  I hope this is useful for you.
