Charging sets my music playlist back to the begenning

Hello all,

Lately my 8GB Sansa clip zip has been starting over the playlist everytime I charge it via usb cable. It doesn not display the “refreshing your media” message, but when I unhook it after charging it will often go back to the main menu and not let me resume my music where I left off, forcing me to scroll (with a considerable ammount of loading/lag between songs) through hundreds of songs to get back to where i left off listening. Is there anything I can do to prevent this?
