Does anyone else experience the same: since upgrading to 3.0, it seems that I can not quit applications. Before, it you pressed the main button for a number of seconds, it actually ended the application from running, and returned you to the main screen. Now, pressing for long time does do nothing, even upon releasing the button I'm still in that application. When pushing the button only once, for short time, then it brings me back to main scree. It appears that the apps are still running then. Anyone have the same, or am I missing a setting or something? Thanks!!!
