Without looking at the code: This is not a problem with Qt but with python. The keyword is GIL, the global interpreter lock which ensures that only one thread is executing python in this runtime instance. There are two ways to have "true" threads: 1) Implement the thread in C++ and bridge it to python with SIP the same way Qt is bridged to python. 2) Use processes instead of threads. Then you can run several instances of the python interpreter at the same time. Arnold
