Closing An Application
Multitasking is a feature that was added in iOS4. Prior to iOS4, when you left an application by pushing the home (square) button, the application would close. Now that iOS has multitasking, applications stay “running” even when you leave them. While this is a wonderful feature, it can sometimes cause issues.
To see the list of running applications on your device, press the home button twice. The list of running applications will show up at the bottom of the screen. You can switch applications by clicking on them. To close a running application, hold down on the application icon (in the bottom active application bar that pops up) until the icon shakes and shows an X in the corner. Pressing the X will close the application. Once the application is closed, you can run it from your home screen to start a brand new instance.
Deleting An Application
To clear the data stored in an application and to sometimes resolve issues, it is necessary to delete (uninstall) the application. To do this, hold down on the application icon until the icon shakes and shows an X in the corner. Pressing the X will delete the application. You will be prompted to be sure you want to delete the application. Once the application is removed, you can reinstall it from the App Store. If you purchased an app, you will not be charged again for reinstalling it.
Taking A Screenshot
One of the wonderful features of the iPhone and iPad is the ability to take a screenshot. If you press the home button and the power button at the same time, a screenshot will be saved to your device. You can access the screenshot by Photos app on your home screen.
Taking a screenshot is useful to show developers what you are seeing. If you have an issue and think a screenshot would help us understand, they are certainly helpful.

(Note this issue has been addressed since originally posted, but may apply if you are using an older version of iOS.)
We have received reports of no sound in our apps on the iPad 2. This is apparently a compatibility issue with the rolling mute feature. To correct this – set the mute lock to “Muted”, then start the app, and then “Unmute”.
Please let us know if this solution does not work for you.
