Ce qui est vraiment bizzare , et qui me rend fou, c est que quand je lance uniquement ce client (sans aucun serveur), je click sur Connect, la connection est etablie..et puis si je click sur Send, ma fenetre a pour title "test" !
On dirrai que le client est connecte a lui meme !! Je comprend plu rien la
