I guess I am instigating the changes, but only because in the text box, as I type, the text shows as a small times new roman (or similar), and I assume that is what will show on post. In the Title text box above, the correct font and size shows.
I think I found the issue; the 'Switch Editor Mode' button, you eluded to BNT, I clicked once and it now looks like the 'correct' font and size now show in the text box. Thanks!!
If it happens again in the next week, I 'm good to go, but any time after that, all bets are off.
Oh sh..........., now with proper font showing, smile icons show as text when selected. Back to the drawing board, I guess.
