Expression wrapping no longer working

Using Mathematica 12.2 on Windows 10.

Somehow expression wrap has gone away. So long expressions (without newline inside them) just extend waaaaay to the right and I have to use the slide bar at the bottom to look at them and manipulate them. I’ve looked for the control for this, but I can’t find it..

And some things come out in bold-face, larger font, etc … probably associated.

What do I do to put it back the way it was?
