I reloaded the "styles" directory from the original installer. The boards are back. This is scary stuff!
I am occasionally dyslexic, that must be where I got the wrong version number. Apologies for the confusion.
I returned and followed your directions more carefully (curse that always-happening "operator error" thing from end users like me), and there are now SOME icons showing up in the new "styletest" that I created. Thank you for pointing the way. I'll keep working on it.
