Dawn,

Just above the Tool Options Bar is a row of a few buttons. Click on the Organize Photos button - that will open the organizer. Then, you can click on a photo and drag it to the editor (go to the task bar, hover over the Editor, when the editor opens drop your photo in the photo bin) or you can right click on the photo and choose "Open in Editor" (I think it's ctrl-I).
