Dear all , Need an urgent help in fixing a bug in my Chat program

Dear all , Need an urgent help in fixing a bug in my Chat program

I have two main loops , one loop is for controling the GUI related activites and the other one is for receiving the data from the chat clients.

Problem :

If i click any of the buttons/controls/manubar items in the first main loop ( while ) it will take 2-5 minutes to run the curresponding activites in the first loop,eventhough the second loop is not receiving any data's from the clients.

PC config : Dual Core 2.44 with 3 GB RAM

I have included my program code(Two Main Loops) also along with this mail.
