Hi Glynn,
first thanks.

ok I'll take care of that, for now I flush the display because it's fast to
code.

I suspected that, but when I did a test (writting a char in a file every time
the main loop started a new loop) I detected some loops completed, without
interacting by myself. Now I think I will first write a loop which will be more

I already do this, I'm looking in twm and jwm, I use two books also and I
bother people like you, I need to have different sources in the aim to
understand, since almost everything isn't in my mothertongue.
so now, about the rest of your email, I won't say everything is clear and
obvious just by reading it, but you gave me enough information to lead my
searches.
