After Deleting a Photo in Preview it still appears in the Thumbnails

Often I take photos and use Preview to review and delete duplicates, or pictures I do not want. When you delete one picture the image disapears, yet the thumbnail renames. Therefore everything then is out of sync. You move to the next photo, and the thumbnail is out. If you quickly scroll to the last picture and then back up, it seems to correct itself but something is not quite right. It means quickly deleting pictures on the fly is now an absolute nightmare. The only way I can successfully do this now is to avoid using Preview and just ramp up the size of the thumbnails in Finder, which is no where near as clear and large as Preview shows.

Anyone else have this, and or know a fix?

See the screenshot below.....once the image has been deleted, the next picture in the sequence is displayed and the thumbnail stays the same. So then when you don't want to delete the next picture and move the next one you want all of the full screen previews are out of whack!

Could you tell us what OS your running? Are you running any "Mac cleaner" software on your Mac (generally a bad idea!) or any other suspicious software?

You've done this before with Preview, right? What has changed that might have affected it?

If you haven't already, try these things:

Restart the computer (of course)
Re-start in Safe Mode. This bypasses certain potentially disruptive processes, and it often helps. Safe Mode is different for different computers, so see this:

Start up your Mac in safe mode - Apple Support

Make a new user and see if the same problem recurs with it

The idea is to find out if the problem is with the Library, with your account, or with caches and login items, and stuff like that. One of these steps may fix the problem, but their failure to work also helps figure out what's happening.

Let us know what happens…
