Blurred Images

Hi everyone,

I have Adobe Elements 2019.

A problem has occurred in my organiser where my images have become blurred when viewed in full screen mode. This does not occurr with the latest images. The last few years are all ok but beyond that all the images are blurred in full screen view.

If I delete the blurred images and get the photos again from my files, they are ok, but I really don't want to do this with all the thousands of images I have in my organiser.

I hope someone can come to my help and solve this problem for me.

Many thanks in anticipation.

Keith
