Remember track playing

My wife and I both have Sansa Clip + players, mine purchased about a year before hers.  When I turn mine off  and then turn it back on, it remembers what track was playing and it picks up where it left off.  Hers will not do this.  Please tell me there’s a way to allow her player to also remember what track she was listening to (so I can have mine back;-).  Thanks. MM

Many thanks!

Did it work? And was it the format or the re-application of the firmware?
