I'm trying to sync apps between my Ipad, a windows 7 desktop PC and a windows 7 laptop. I can transfer purchased apps to both desktop and laptop. However if I do an app sync on the laptop and then sync on the desktop, the box for app sync on the desktop becomes unchecked, and if I then check it and do an app sync on the desktop, my screen icons are all messed up and I have to rearrange. The same happens if I sync on desktop first. It seems I cannot sync with two PC's without messing up my icon arrangement. Anyone else have this issue?
