As I analyze what happened in this "situation", another thing that
happened was that the above rule moved some of the "New" messages back
into the same folder.  But...  I ended up with a _copy_ of each "moved"
message...  My C knowledge is about 40 years out of date, so reading what
you guys wrote is beyond my skills... :(  

However, just wanted to point out that a {pre[,post?]}global "move" might
be doing a copy if source & destination folders are the same...

BTW, I've never used {pre,post}global filtering... except be accident
today. LOL

HTH,
