thread problem

Hello,  
       my program use two thread, one stay in gtk_main() and the 
other receive data from the net and draw somo control on the main 
window. 


void my_main_loop()
{

  // Init thread and gtk 
  ....

  // Create main window
  ....

  g_thread_create(mythread....)

  gdk_threads_enter();
  gtk_main();
  gdk_threads_leave();

}


gpointer my_thread(gpointer)
{
  
  for(;;) {
 
   ....
   sm = select(...);

   if (FD_ISSET(......)) {
 
    gdk_threads_enter();

    // Process data and draw/update some control
    ....

    gdk_threads_leave();

   }

  }

}

Under linux and gtk-2.0 all is ok and work soo good. Under Win2000 
SP2 all go wrong. I have a dead-lock : the main thread is stopped in 
a function called by gtk_main() in USER32.DLL; the secondary thread 
is stopped to gdk_threads_enter()

Anyone can help me ? There is a problem with the gtk-2.0 ? or i am 
wrong ?
