Updated DX from froyo to gingerbread. Button lights have a mind of their own. On froyo they would go out, but sleeping the phone and waking it up would bring back the lights. On GB, when the lights go out, they stay out. Sleeping and then waking up doesn't restore the lights. Sometimes they come back on their own - who knows why! Anyone know how to force the button lights to come back on again without rebooting? Tried resetting or toggling display brightness, but that doesn't do it.
