Hello,

   I am learning the Interactive Simulation function in the OpenModelica. I looked through the user guide and there is one chapter talking ablout interactive simulation. UsersGuide interactive-simulation I run BouncingBall model as the video does. When I checked the "Interactive Simulation" and run the simulation, everything worked fine. If I checked "Simulate with steps" tool and click "run" as the video does, the software will froze and later crashed.

  I just want to control the simulation process outside the OpenModelica, such as use python with opc-ua to control the simulaton, take one step when I want.

  I wonder is there anything I missed? Or the software has indeed some bugs with the "simulate with steps" function.
