An alternative solution would be to update to a more recent version of
Sugar. Since 0.86, we have had a stop button always available on the
main toolbar of every activity, making it easier and more obvious how
to exit an activity. We've also changed the default behavior of the
launcher to open the most recent instance of any activity, so to open
multiple instances of the same activity takes a specific action on the
part of the user. Since these two changes, we've seen a reduction in
the problem you are describing.
