Any idea how I could check that?

I get 59218.
The default value of 51954 is detected in several files when I run from a terminal « grep -r 51954 /Applications/Alpha.app ».
But for some reason, it apparently looks interpreted as busy and another port number is (randomly) chosen.

I get 1

I get 127.0.0.1


To further document the behaviour of the error message window: the « OK » button is initially displayed in blue and I need to click it, changing its aspect to un-coloured transparent, before I can use Alpha. The error message window does not disappear however: it remains with the un-coloured « OK » button. And I « need to search » the new windows that I open in Alpha: command-N results in an Alpha status line message indicating « untitled  'command symbol’1, but the new window is nowhere to be seen first. A sure way to make it appear is for instance to start a search by command-F.

Thank you for your reactivity!
