I setup a desktop background slideshow in a folder with over 2000 jpg slides but instead of cycling through the slides completely the slideshow keeps starting over with the first slide. I can't pin down exactly when it happens because the desktop isn't always visible, but it's visible often enough for me to see that it's not getting very deep into the folder before beginning again. I have a Dell inspiron, i7 processor, 8gb ram, 1tb hdd. Suggestions? Thanks!
