Hi, I'm new to iPad 2, and it is my first Apple/MAC device. I've downloaded the PDF support document but can't find answer to this problem. (BTW, I found that loading to Books app provides most efficient access to support doc.)
Problem: I sent an excel spreadsheet from Windows 7 laptop to iPad via Yahoo mail. I was happy to see I could open it, but now it won't go away! I must have chosen an application with which to open, but don't remember what it was. I've clicked here and there on the spreadsheet but find no way to close it. I can't view my mail. My daughter has told me that MAC folks are very eager to help out, so I'm throwing myself on your mercy. Thank you so much for any help!
