[NWZ-E380] Can you lock?

[iliketraisn69]

Rockboxing my Sony nwz-e380 was one of the better things i've done this month but i have one problem.

I cant't lock it whatever buttons i try! I've tried everything but it just doesen't want to.

I just wanna know if it is possible to lock it during playback because i hate bumping into something and stopping or changing the song.

Thanks in advance.

On my Sansa Clip+ you lock it by press the Home and Select buttons at the same time.  Looking at the controls on the E380 it looks like the equivalent would be to press the Home/Back and Option buttons at the same time?
