Hello, I sure hope you can help me! I got an email from my daughter with a picture file (paper clip) attached. It wouldn't open and I got the box pop-up that says "open with". I forgot to uncheck the box at the bottom that says "use this to open all files of this type" or something like that. Anyway, it didn't open it and now every file she sends me is in that format I put it in (quickview) and I don't know how to change it back, or what the file was she sent, because now it all turns into quickview and I can't open it either! Please tell me how to get to this box and change it back!
