cant remove pictures from organizer
Why not? What exactly are you you doing to find you can't remove photos from organizer? Have you tried going to:
Edit >> Delete from Catalog
You first need to select the photo you want to delete then do Edit >> Delete from catalog.
Don't make a mistake to delete from the hard disk because this is not what you want to do. You want to delete only from the organizer catalog so that it doesn't clutter your workspace unnecessary.
Hope this helps.
