Thank you for your answer, that was indeed the reason. Actually, I didn't explicitly
add this flag manually, but through the wxWidgets GUI, that has a "Terminal
configuration" dialog with the "persist" toggle option.

The problem is that if I don't set this "on", then the plot/GUI doesn't stay on the
screen, and closes instantly. So, as usual (I mean, this is what I do with Windows),
I add:
pause -1
at the end of the file. And, for some mysterious reason, gnuplot just ignores this
statement, and has the same behaviour (closing the window when finished plotting).

So, what's the best way to go ?

Yes, I indeed used to use the "wgnuplot" binary. However, I never had to bother to 
consider this "persist" option (discovered that today).

;-) You are absolutely right, what I meant (lets be precise...) is that trying to
close the window by clicking the usual button didn't do anything, and my faithfull OS 
noticed this behaviour, and kindly asked me if I'd like him to "force it" to close 
for me (in some way I ignore !).
