I cannot figure out what is wrong when i try to copy an application from my tungsten E to the sd card. I am following the manual directions, but when i get to the "copy" screen, no applications show up to highlight or copy. Why is this? What am I doing wrong? My sd card seems to be fine. It's been reformatted and it shows it's empty so I don't understand why nothing shows up on the handheld screen to copy to the card.
