I tried to Freeze and it seems to work!

In Image1 the Eiffel Compilation Output window after Project>Freeze command.

In Image2 the External Compilation Output with some messages: I don’t know if they are errors/warnings.

Then I tried to run the application with the Run command.
In Image3 you can see the Debugger Output:

In Image4 you can see the Terminal window with output messages from the application:
I tried to run the application two times.

And finally in Image5 you can see the Eiffel mail window with the HEIR class displayed:

Do you see something wrong with these outputs?
Perhaps I can keep on working with the Tutorial..

Many Thanks and regards
Alberto
