Many terminals have two modes, the "normal" mode and the "keypad" mode.
The arrow keys often send different character sequences in the different
modes.  What's happening is that your terminal is getting switched from
one mode to the other and not switched back.  This is probably a result
of a problem with the termcap or terminfo description of your terminal.

The easiest thing to do is use bindkey to bind both the keypad and normal
arrow key sequences to the same ZLE actions.  Most probably that means
something like this:

bindkey '\e[A'	up-line-or-history
bindkey '\e[B'	down-line-or-history
bindkey '\e[C'	forward-char
bindkey '\e[D'	backward-char
bindkey '\eOA'	up-line-or-history
bindkey '\eOB'	down-line-or-history
bindkey '\eOC'	forward-char
bindkey '\eOD'	backward-char

If you use the vi keybindings, which it looks as though you might from
your description of the symptoms, then you should use:

bindkey -v
bindkey '\e[A'	vi-up-line-or-history
(etc., putting "vi-" into each of the above examples)

Hey, PWS:  You might want to mention keypad mode in the FAQ answer 3.8.
