PenPusher gives me the error "MoSync error: 40031", why?
This error is thrown as the Android device isn't able to obtain a GPS lock. One way to avoid this error is to disable GPS in the 'Options > Settings' menu.
An alternative that should be used with care, as it would remove any unsent PGC data, is to reset the applications configuration through the Android application manager (Settings > App Manager > PenPusher > Clear Data). Once the configuration has been reset the user details must be re-entered into PenPusher.
