Ultimate. Right click on a thumbnail and choose Auto Rename Images. You see the sets listed there
Anthony,
I tried everything I could think of to repeat what you see.
I used EDIT Preferences Auto Rename as well as the Right click on one or multiple selected thumbs and using Auto Rename, I cannot get it to fail ever.
I used the preset naming conventions, and even added one and removed one manually to see if that was retained after closing QU and reopening.
I could not get anything to go wrong.
Is there any other item like print size, driver settings, profile changes, or even a folder change that is not saved?
If so, that is a simple fix.
Fred
