Sansa E-140 Pausing issues

HI!  I have a SANSA E-140 that works quite well.  My ONLY issue with the unit is more often that not when I pause an audio book for a minute then resume it will resume farther in the book than where I was actually at!  This gets a little annoying because, I then have to search for my last spot in the book.  Any help here would be great.  And before you ask,  yes the battery is in good condition.
