With the new release, I experience issues when I want to stop the simulation, e.g. the demo scenes.
As an example: The simulation crashes when I press the Stop button after starting the Paint Ball Emitter example (can be found under the tab Window > Simulation > Demo Scenes > Particles > Paint Ball Emitter).
I am using my own python scripts to generate my own scene, and I also run into the same problem there.
Any idea how to overcome this issue?
