I loaded PE7 and it located my Photoshop element calalog. That was fine however PE7 created duplicate or edited files. Not good when you photoshop elements catalog contains 20 thousands pictures. Is there a way to prevent PE7 from creating a duplicate still image. I had to delete the catalog and start over/
I've never seen or heard of this, md, and I don't know any reason this would happen.
Since this is a Photoshop Elements problem, I'd recommend you try posting your question to the Photoshop Elements forum and see if someone there can help you.
