Aperture Library: folders appearing in my "pictures" folder
In my "Pictures" folder (in my Home folder) - the same folder my Aperture Library is in - folders are appearing containing images I've imported into Aperture. Is this normal? It seems quite random which pictures show up. The folders are named the same as the projects I've created in Aperture, but they don't always have all the images from that project. Can anyone help? Why is this happening? Have I accidentally changed a setting?
The Library Location I have set in Aperture's preferences is: ~/Pictures/Aperture Library.aplibrary
Am I right that all images imported into Aperture should remain in the Aperture Library (i.e. the little white box)? Why are some going into the Pictures folder adjacent to the white box?
