In the converted Delphi project I started with a .dpr file that
contained all active code except for two units to read Ini files mor
easily and to create Unix style hashed passwords.
When it was done it still used the dpr file as the main program
source.

My program is called LicMgr because it ie meant to create and send
demo licenses to people asking on our website.
For this it needs to:
- Read incoming email (Indy 10)
- Parse the messages for validity
- If valid:
  - Create a new login entry on the server, so it needs to:
  - Read the password file from the server using FTP (Indy10)
  - Add the new entry to the end
  - Make sure there is not already a duplicate
  - Upload the modified password file (Indy10)
  - Compose an email to the customer with a link and login
  - Send the email (Indy10)
  - Log all activity including saving who is getting logins

Well, I created a new project from scratch and added in my units,
still the same problem.

I will try to make one from scratch and see what happens.
If still the same then I might take you up on that...
