I am using explorer.exe to look at the list of files in the stage and KY directories.

To try to summarize, explorer.exe shows the dates of all 12 like-named file pairs (not including KY3.gif) in these 2 directories to have different stamps.

My application and diagnostics (using mtime) I've run show all 12 file pairs have the same stamp, the stamp of the first file, or the 2nd file (stage) stamp is incorrect.

But the KY3 test showing the stamps of the 2 KY3 files initially, then after an open and close of each, a 30 second wait, and then another open and close of both, yielded correct results.

I will look into the plugin suggestion. I can say now that I've never installed any plugin that had anything to do with explorer.exe. I am feeling a little lost.
