Why can't you release an update that stops the volume keys sticking on MK850. Blogs have been full of this for years and I suppose you have made money selling replacement models. Fully updated the up volume OR down volume will randomly stick. No good late at night when volume goes to 100 !!!! This tends to happen if the volume key is held down OR if it is tapped at a speed below PAINFULLY SLOW. Just FIX IT !!!!!!
