If the screen has too few lines or columns to display all of the windows
entirely, TextPad.refresh will crash with the following error:
Traceback (most recent call last):
File "meshtastic/meshwatch/meshwatch.py", line 431, in Clear
self.TextPad.refresh(0,0,self.y1,self.x1,self.y1 + self.rows,self.x1 + self.columns)
_curses.error: prefresh() returned ERR
A nice solution would be to rescale the windows according to the screen
size but as a first measure, quit gracefully instead of crashing. This
change does not protect against users shrinking their console or
increasing font size after startup
(cf. datagod#8)

For those having stability issues, I happened to trip over this:
curses — Terminal handling for character-cell displays — Python 3.10.0 documentation 2
A bug in ncurses, the backend for this Python module, can cause SegFaults when resizing windows. This is fixed in ncurses-6.1-20190511. If you are stuck with an earlier ncurses, you can avoid triggering this if you do not call addstr() with a str that has embedded newlines. Instead, call addstr() separately for each line.
