REVscene Automotive Forum - Ipad 2 memory storage problem

Hey guys, I have a little situation with my moms Ipad 2. She is currently using the new IOS5 software. The problem is that every time she plugs the pad into the computer it shows on the bottom that for the, "others" part for the memory is completely full, when there is completely nothing she has installed or downloaded on to it. She has tried to restore and download again every time. It does go back to normal, but then a few days after it goes back to the same. Do you guys have the same problem? If so, do you guys have any solutions to this problem? Please and thank you.
