Never mind. I found the box to un-check under Folder Options/View. Of course I checked the obvious places. I just didn't know what to look for to turn that view off. It's:
"Show popup description for folder and desktop items"
Now how it got checked, I'll never know. It's so Windows. Since I don't know what the defaults are, I didn't want to reset it to defaults because that might give me more things to find and fix.
