I'm developing a board game with wrt. And now I have a problem after publishing the app to ovi store. It failed in media quality test with an error of 'The application does not enter into pause state after suspending the application in the background.'

I have a timer in the application and when the home button is pressed the app is continuing to run and the timer is so on. I want to exit from application when home button is pressed. So I want to learn how can I understand the home button is pressed event with wrt.

Do you have any idea about that?
