For those who are already using version 1.02 or earlier :

I added a little utility that moves some files from 1.02
format to the newer 1.03 format.

you'll have to copy this file (102to103) to the maildirectory.

The files :  mailbox.dat
             address.dat
             singlbox.dat

are already in this directory. copy the utility 102to103.exe to the 
same directory and execute it. (Of course you already made a
backup so it is not necessary to say to make one since you 
always make backups before installing new software don't you ?)

The 102to103.exe copies the original files to the files with 
extension old and creates three new files with the same extension 
as the original files had.
