This is probably a stupid and dumb question but I´m totally confused. In PS CS when opening images they have always appeared automatically Fit On Screen. I must have pushed a button somewhere because, all of a sudden, the images open at 25% and NOT at 30,3% as they used to. I can of course always push the Fit On Screen button and the whole window screen is filled but HOW can I make this automatic -as I used to have for years??? Please help!
