Netfront is the browser used on CLIE devices.  Sometimes it will cause a crash when you are playing ShoutCast music and you switch to another application (for example, by tapping the Home icon).  This is due to a conflict between Netfront and Pocket Tunes.  Netfront is trying to close the Internet connection, and Pocket Tunes is trying to keep it open (to play streaming audio).

To fix this problem, start Netfront on your CLIE and follow these steps:

1. Tap the upper-left corner of the screen to display the menu.
2. Select the "Options" menu.
3. Select the "Netfront Settings" menu item.
4. On the bottom-right, you will see a 1/4 page scroller.  Click the arrow to go to page 2 ("Connections").
5. Next to the option for "On Termination", select "Never disconnect".  (You can also select "Prompt", but make sure not to disconnect while ShoutCast music is playing.)
6. Tap OK.
