Thanks. I have a fresh install of Windows 8. I'm wondering if the adhesion improves over time, as with some of my other screen protectors for other touch-screen devices eventually do, but those were wet-apply films that shrink after the liquid evaporates, creating a tighter bond between the film and the glass. This one is obviously different, so I'm not sure if the "wait and see" approach will work, but your experience of moving to another OS makes me think that the time it took you to install the new OS allowed the film to cling to the screen more securely. In either case, I contacted photodon about my issue. Until then, I will test the responsiveness periodically to see if it improves over time. I can only hope because screen-protector availability for this device is rather slim to none.
