Disappearing Photos
I have just starting using Aperture 3, following Scoppettuolo's manual. I imported a few photos, created a project and added these photos to this new project. Due to an inadvertent key stroke all the photos in the project disappeared. They still show up in the project where it is listed under "Recent" in the Library inspector and also under "Last Import" but do not show up under the project listing under the "Projects" heading. They are not in the trash. When I "mouse over" the project name it indicates the number of pics assigned to that project although the browser window is blank. Where are they and how do I "reinstate" them in the project?
