rewind before the beginning of a file

[joe_uk]

is there a setting that allows me to rewind before the beginning of a file and goes to the last part of the previous file?
when i rewind it just stops when it reaches the beginning. the original firmware allowed this. im using norbu's new build.

the manual says in WPS Key Controls :
"Left

Go to beginning of track, or if pressed
while in the first seconds of a track, go to
previous track."

if i press while in the first seconds of a track it just stays at the start of the current track.
