After editing a photo with photo shop elements 12, I found all the thumbnail in the same folder have an overlying grey box icon. The icon also sappears on pictures in the pictures folder that are not in a sub-folder
The file association has not changed, and I do not let adobe organise the files - but something has obviously happened.
When I look in the properties box, the same icon appears.
Does anyone know what this means - and how do I remove it please?
