Usually I insert memory card into reader ( connect with USB ), autoplay dialog box display to ask choose. Now I don't know what it is happen, autoplay didn't run, autoplay dialog box did not display while I insert a memory card into reader. I did many way to try run autoplay -- select autoplay with picture, clicked autoplay, it did not run. Re-setup USB connction, did not help. Re-start PC few times, did not help. Post this help two times, but no one answer it. Is there anyone know how to let autoplay to run ?
