For weeks now, I've been wrestling with a problem that keeps getting solved but then keeps recurring. One of my folders, which contains almost 400 pictures, keeps vanishing. When it vanishes, all 400 thumbnails in that "non-existent" folder get an "unconnected" question mark in the upper left corner. Sure enough, when I look in Windows Explorer, the folder doesn't exist. I don't actually DO anything in Windows Explorer. I learned long ago to stay within Elements for this sort of thing. But Elements isn't solving the problem. Can any of you?
