Please try the newest development version which you can get at:

`setopt nopromtcr' -- which has only recently be added to the FAQ.

This is still there... no doubt someone will have a look at it.

We have this discussion again and again... Completion in quotes is
different in zsh because some time ago it was decided to let it work
there (almost) as without the quotes. So if you do ls "one t<TAB>
zsh doesn't think that the quotes are intended to just quote the
filename because for that you simply don't need the quotes. If you do
ls one<TAB> zsh will give you ls one\ two\ , quoting the string as
needed.
However, the behavior shown in your mail looks really weird, I might
have a look at it (but quoting and completion is a terribly
complicated issue).
