P.J. is having an issue with his photos folder, where the cursor is jumping to the top constantly in Windows 10 file explorer. Leo says that is a feature in Windows 10 where it caches thumbnails after you open a photo folder. Youll notice a green line at the top growing from right to left. Once done, it jumps back up to the top. So you can either turn off that feature in the settings, or you can just wait until it does the caching. Also, check your sorting option is by capture date. You can also change the size of the thumbnail to make the caching faster.
