Well ... duh. That was it! I'm glad I posted those last screenshots and that it was such a simple solution. Christmas cards for life!

P.S. I also tried reinstalling CCleaner. Still no joy.

Attached.

It does keep *something.* It remembers the last settings used for Duplicate Finder. If not "cache", what would be the correct terminology, please?

To wit, I created two folders on one drive: Folder1 and Folder2, then I copied the same file to both folders, then I pointed Duplicate Finder to both locations, hit Search and... No joy. Where it was working, now it is not. That's about as basic I can get for troubleshooting. Any other suggestions?
