A third-party application is not working as expected
If you are trying to use a third-party application that was not designed for BlackBerry® devices with a touch screen, you can turn on compatibility mode to allow the application to work on your device. When you use an application in compatibility mode, you must use your device in portrait view. If an application requires a keyboard, the SureType® keyboard appears.
To turn on compatibility mode for a third-party application, try performing one of the following actions:
On the Home screen or in a folder, highlight the application. Press the Menu key. Click Compatibility Mode.
To turn off compatibility mode, repeat the steps that you performed to turn on compatibility mode.
