When you press the stop button it will wait for all of the threads to finish before you can start again, the start button will become available when all of the threads have finished. If you try to close it before the threads have finished you will see the same thing happen, it will wait for the threads to fully finish before it will actually close down.
The more threads you run the longer it will take for them to finish, if the number of threads being run is appropriate for the connection it should take no more than a couple of seconds for the threads to finish as there will be far fewer threads waiting to connect.
