i know how to set home screen and lock screen with pictures but here is my question. when i went to first set my home screen i selected the picture i wanted as my background and it ask me to "move to scale". so i set that up and it appeared just how i scaled it and wanted it. when i went to select my lock screen pic it asked me to "move to scale" but it wouldnt let me move the pic around how i wanted it. now it is not letting me "move to scale" for either background or lock screen. what is going on or happened you think?
