M230: Pause button is resetting my playback?

One of the features I really liked about the M230 is that when I paused the player, I could pick right back where I left off before.  A great feature when you listen to podcasts!  But now, even though the player is paused where I left it, once I push “Play” the player rewinds to the previous recording.  I have updated the player and firmware, to no avail.  How can I fix this problem?
