Elements Organizer loses photo selection
I am seeing a very strange problem in Photoshop Elements Organizer. I have my photo catalog open and am looking at the grid view of a folder, then double click in a photo to look at it in detail. This works, but then a little while later the view of the photo closes and jumps back to the grid view of the folder. The time this takes varies from a fraction of a second to about 10 seconds. I am not touching the keyboard or mouse when this happens.
A similar thing happens if I just select a photo. I select a photo and a tick appears on it. If I then just nothing at all and wait, the tick disappears. Same if I do "select all" - it initially works and then the selection just goes away of its own accord. Needless to say this is infuriating.
I initially observed this in Photoshop Elements 14 running on Windows 10. The installation was done a few months ago on a new computer. I never noticed this effect on my old computer.
Since I have been thinking of upgrading anyway, I decided to install the trial version of Photoshop Elements 2020, and I find that this does exactly the same thing.
What could possibly be the cause of this strange effect? I am not seeing erratic behaviour in any other application.
