If Enable GPS is on (or set to "on" from "off") it could search, and if it fails, ask e.g. "continue search or quit?" and if the latter it wouldn't search anymore. Enable GPS would still be in its "on" setting so that whenever maemo mapper is started with the GPS at hand it will use it - otherwise not (without having to use the menues). Not a matter of life or death, obviously, but it would be convenient.
