Stateflow Tabs Stop Working After Running A Simulation.

Hello, my simulations run as expected and exit without errors. However, I noticed every time after I run a simulation and click “Stop Debugging”, the tabs labeled “Simulation, Debug, Modeling, Format, etc” at the top of the screen no longer click and drop down. I’m forced to restart the entire application after a full simulation run. I also noticed when I do a simulation step by step, by clicking “Step Forward”, I have no problems. Why is this?

Hi Amjad,

This issue happens because stopping debugging after a full simulation can sometimes cause the Simulink or MATLAB user interface to freeze or become unresponsive. This is usually due to a glitch in how the program handles resources and windows when you abruptly end a debugging session. Sometimes, background processes or hidden windows (like debugging panels or dialogs) may not close properly, and certain resources or UI controls aren’t released as they should be. Low system memory or conflicts with graphics drivers or third-party add-ons can also increase the chances of this happening.

While when you use the "Step Forward" button, the simulation only runs one step at a time and doesn’t fully start or stop the debugging process, so the interface remains stable and responsive. That’s why you don’t see the problem with step-by-step execution. In summary, a combination of how debugging sessions are managed and possible resource issues can cause the menu tabs to become unresponsive after a full simulation run.

Hope this answers your query!
