duplicate mail

[Brian <zarnce zarnce com>]

Ok I like balsa but its getting on my nerves.  Every time I start it  
and sometimes when it checks for mail it downloads everything from the  
server giving me dups.  I end up at least twice a day going through all  
of my old mail to mark it read.  Whats going on.

Setup:
External Mail server - Freebsd/qmail/pop3
local balsa workstation - Slackware/balsa using mbox (Maildir setup  
doesn't make sense) NO GNOME (I run Windowmaker thats it)

any ideas why it is doing this? I am running Balsa version 2.0.16

Thanks
   Brian
