Until recently, when I opened WLM, a message popped up above the notification area worded "collecting and receiving mail" but this has now been replaced with an envelope in the notification area.  This shows a yellow indicator to say mail has been received but if no such indicator appears I do not know whether it means that I have no mail or if WLM is not working.  Is there any way that I can get back the "old style" notification which I assume was replaced by the envelope indicator when WLM was automatically updated at some time.
