Hello,
I hope you can help me to find the solution.
I use ERIC 4 as environment for python.
I developed like a chat program, with a server and multi clients.
First, it works when I executed it in DOS. But when I integrated the
program in QT4 interface .py it always blocks.
This is my interface server_code.py:

This interface should realise the communication between many clients
according to the client adresse
In a python forum someone proposed to me that code, But when I
executed it an error message appear and indicate that "pythonw.exe
encountered a problem and must close. Excuse us for the incurred ...."
I have windowsXP.The code is:

Thank you for reading my e_mail.
I am waiting for your answer even if ...
I accept any other solution or links to help me.
I wonder if the client code should also be modified.
