I just upgraded from PureVisionHD 4.6 to PureVisionHD 4.8. Now, I notice that when scrolling across my screen in Moving Pictures, or on the home screen, the issuance of "click" sounds is inconsistent. With 4.6, every move had a distinct "click" associated with it. Now, with 4.8, it seems as though I am only getting a sound on every other selection, but not consistently. A bug perhaps?
