I have a Touchpad 32 on the Touchstone and I have it doing photos for the exhibition setting. After awhile, it gets stuck on one photo and it will not switch. Even if I turn it on, then leave it, it goes back to that one picture and stays. I have paused and un-paused it to no avail. The only workaround I have found so far is to delete the picture and re-boot the Touchpad (if I don't re-boot, it goes back to being stuck on the deleted picture). Obviously, if I delete a picture a day, I won't have many pictures left soon, so I need a better solution.
