Ah, so with the example you provided there would've been only 1 qthread object and you re-used it? Thats indeed not a good idea, each thread should run only once, so you should create a new object each time you want to run something in a thread. > > Can you leave out the network-system from your app, replace it with some > > kind of busy-loop, i.e. > > > > while(True): > > time.sleep(.5) > > > > Does that still lock up the widget until you terminate the thread?

The reason that the thread is not terminating in the code above is that you're using self.quit(). If you look in the API docs, you'll notice that quit merely ends the event-loop of the QThread. But in your example you never start the event-loop in the threads, so there's nothing to quit. Changing that to use self.terminate() makes the example code work as expected, the label is not updated for PushButton 2. If thats not the case for you your Qt and PyQt versions might be interesting, maybe its a bug in either that got fixed.
