Thanks for the quick reply.
I hope this is going to make sense to you.
Click on Edit Images Info button brings on screen1. This is a gallery with 20 images. You can just see image 5 at the bottom of the screen. Repeatedly pressing tab takes me down the screen. When I get to 5 it continues 5-and-and-6-and-and-7 – At 7 the page finally moves up but you still can’t see the cursor. Have to use scroll bars. If I continue to tab down the page I finally stop at screen2 with image 18 showing. Using the scroll bars I can shift to screen 3 with the with image 19 visible. Finally I can see the bottom line – image 20 – by going full screen in the browser using F11. (Going full screen from the outset doesn’t fix it.) If you can’t readily replicate the problem, don’t bother any more, I can live with it.
I have only 2 other plugins, Content Aware Sidebars and Tablepress. With these deactivated and changing to 2019 theme and deleting the browser cache the problem remains exactly the same. I don’t know how to delete the wordpress cache.
Thank you, Mike
