In the Settings menu, there is an "Auto Refresh" option which you can set to "Never," but there is also a "Ticker Refresh" option which you can't turn off. What do each of these things control? Is the Auto Refresh just for when the app is running? Does it affect the widget at all? Does the Ticker Refresh option only affect the widget? Does it have any effect if the widget is not being used on any homescreen? Thanks.
