window not responding

[Raghul]

hi
I am working in making a jabber client.I made upto chatting with
each other.Any number of people can be simultaneously chat.My problem
is that If I am initiated to talk then the application works
fine.Suppose if my friend initiate the session by sending message the
window goes on not responding.

What i done is that i used a class named dialog for chat
window.When i dble click on the roster list the window is opened and
can continue chatting .Suppose if they initiate the window appears by
printing the message in the text message box and goes not responding.



Pls Gurus give me a solution.


Thanks in advance
