Problems with cursor position and hotkey commands in nano v.4.3

[Fergus Daly]

Anybody else having problems with cursor position and hotkey commands in nano v.4.3?
Specifically, having loaded a text file (DOS- or Unix-terminated) for editing and having used
Ctrl-K to delete a line, then subsequent cursor movements are all over the place (sorry for
non-technical description - cursor does not follow keyboard direction) and subsequent
hotkey commands (Ctrl-K for more deletions, Ctrl-U to paste) are annulled.
