Thanks Tim,

Had so many sticks in the fire I forgot that approach; should have been 
one of the first tests.

Tried that this AM and it didn't work but an error message popped up 
long enough to see that it had a problem with gnome-shell-3.10.4-6.fc20.

Yum erase/install gnome-shell gnome-tweak-tool and all is well in happy 
land.

Rhetorical question of the day: "Why are gnome3's hidden directories 
named .gnome2 ?
