After recently installing Rockbox 3.2 on my iPod photo (4th Gen), I've noticed that I can't shut my iPod off, with RB in use, then plug it into an outlet to charge it's battery up without it wanting to come on. In fact, the only way I can do it is to revert back to the iPod's original firmware. Is this normal? Or could this be, possibly, the result of a bug?
