I've come across a problem with some programs that I'm re-installing on the 680. Some applications (usually games, so its not that critical) capture the power button to use as a control button. On the Treo 600, this wasn't a problem, because there is another application button that you can use to change to the launcher when you're done with the game. On the 680, there isn't. I've found applications that capture all of the row of four buttons, and don't have an "exit" menu option, and don't seem to have a way of exiting the application. Is there an alternate way of getting to the launcher, or a non-overridable key combination that can be bound to the launcher?
