The BlackBerry Curve smartphone is capable of running hundreds of third-party applications, ranging from productivity tools to games. These apps can often remain open or may not close incorrectly, which can have an impact on the device's resources. This may cause the BlackBerry to freeze up and stop receiving input from the user. If you find yourself clicking away on your keyboard and the BlackBerry is not responding, you are most likely experiencing a system lock-up. This problem can quickly be remedied by a hard reset. You'll need to pull the battery and allow the Curve to restart.

Tips and warnings
- When exiting an application, touch the BlackBerry logo key and select "Close." Pressing the "Hang Up" button will return you to the phone's home screen but it will leave the application running in the background, consuming the phone's limited resources.
