Not a big deal, but can someone check whether this is an issue with the 4g grayscale iPod target only or a more general issue (on other iPods at least)?
Not sure whether I've never noticed this or just accepted it as normal, but if the very first button that you press after booting Rockbox is the button in the center of the wheel, it won't have an effect, unless you've touched the surface of the surrounding wheel area first.
