I'm test this script in windows xp (PHP Version 4.3.0)....... but 
 
this script works in windows xp (ph 4.3.0) with 2 or more users connected...... 
however, when i try to use this same script on my linux box (mandrake 8.2 php.4.3.1)... and i can't send 2 or more messages without send a some message in another connection.
