Maybe that's why there's an option to "Exit Navigation" in the menu of the GPS app. A lot quicker than switching to a task killer if you ask me!
Ditto. I was able to reproduce the behavior (Browser using GPS when in the background) when indoors (because it keeps trying to get a fix I think). Will try it outdoors later. However, as you said, much better to just turn off GPS; not only is it easier, you do not have to worry about other apps trying to use it (I have a lot of location-aware apps).
