I just redid a show, and reduced the size of all my jpegs to < 100k each (most are 50 or below)... It seems to have helped to reduce the jumps and other problems when running the show on another computer. On the 'old' forum, someone posted a tip about using background images... something about the "hide" function that enabled you to store a picture only once in your final project but to use in multiple times on various slides.... My brain is trying to wrap around that one, and I would like to hear from anyone who could explain this trick, for further slideshow optimizing. Thanks Brian
