OS can be accessed from R6 screen, Ballot Station 4.1.0.0

Discoverd during Travis County demo:

R6 was running Ballot Station 4.1.0.0.

A staff person from the County Clerk's office was "trying out" the R6  (and
we all firmly believe was sent in solely for the purpose of trying to mess
the unit up). She used the edge of the voter card to tap vigorously (one
could say 'pound') at the bottom edge of the touchscreen.  By doing this,
she was able to minimize Ballot Station and bring up the OS screen.

Mike was able to tap at the bottom of the touchscreen to make Ballot Station
come back up, but it didn't look good to the Travis County selection
committee.
