# Stop application properties

These properties define **if and when** the external application launched by the element should be **automatically stopped**.

### **Stop Application Options**

| Option                             | Description                                                                                                                                                                                    |
| ---------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **When switching to another page** | Automatically stop the external application **when moving to the next page** in the presentation.                                                                                              |
| **When closing the presentation**  | Automatically stop the external application **when the presentation ends**.                                                                                                                    |
| **Never stop this application**    | The application **will not** be stopped automatically. This is only recommended when combined with **"Do not start this application when already running"** to avoid restarting it repeatedly. |

### **Remarks & Important Notes**

* **Stopping Mechanism**:\
  PADS4 will **kill** the running process of the external application to stop it.\
  However, **any child processes** or additional processes **started by that application will NOT be stopped automatically**. You will need to stop those manually if required.

* **System Performance Warning**:
  > **Important**: **Always ensure** that external applications are stopped properly.\
  > Failure to do so can cause **memory leaks**, performance degradation, or **system instability** over time.

* **Recommended Usage**:
  * If you set **"Never stop this application"**, ensure that:
    * The app is properly managed elsewhere.
    * You are also using **"Do not start this application when already running"** to avoid multiple instances.
