(Or any document transferring application I think).
When I open iTunes on my PC (running Windows 7) and go to the apps and then scroll down to the file sharing apps and click on one (GoodReader for example), the contained files appear. If I leave that view up, at some point the files disappear and the box becomes blank. I never see this happen, it happens when I am not looking and I don't know if there are any actions I make that causes the disappearance.
From that point forward, if I drag files from the PC's document library into the sharing app's documnet box they do not appear there, but they do get stored in the app (I know this only becase I go to the iPad snd check the contents in GoodReadser for example).
Can someone explain to me why they are disappearing or what I might be doing to cause them to disappear?
