I am another Comcast customer and started having a problem some time during the day yesterday. In the morning everything worked. Now I have all my mail downloaded but there is NO message list or preview pane in either of two accounts.  I can see the most recent on screen as if opened, but cannot access anything prior to its arrival - unless I delete it!  I have unanswered mail that I cannot answer.  Someone suggested a system restore but I will lose all the mail downloaded in that time and it no longer exists on the Comcast server.  I use Norton security suite supplied by Comcast but that does not appear to be an issue - but Comcast is - they will not handle it unless I sign up for their paid "signature" support -  if they even know how!

PS - you cannot notify me at my Comcast address for obvious reasons!!!!!
