Hi:

The mail program hangs up requiring shut down and restarting.  After doing this it's common that all emails appear 
twice.  Is there an easy way to remove the duplicates?

I feel your pain!!

I have been trying ways to delete duplicate emails for over a month. NOTHIN=
G WORKS! Every single SeaMonkey and/or Thunderbird add-on crashes or at the=
 very least locks up - even if I first run the add-on through the Extension=
 Converter before install! The most I got so far, is the add-on to install =
but not work.

Do you use IMAP?
I wonder if using POP3 would help since the mail is deleted from the server after
downloading.  Or that might not be related to your problem at all.
