Different hard line wrap behavior with neocomplete

Hello:

I experience a different behaviour regarding hard line wraps in Vim
(7.4. on Ubuntu) and enabled neocomplete package.

Without neocomplete, I have set up Vim in a way that it inserts a hard
line wrap while typing. That means, when reaching the given textwidth in
insert mode, the line would break.

With neocomplete enabled, however, the wrapping of the line becomes
visible only on exiting insert mode or starting a new line (i.e.
pressing return). Up to then, the display looks like I would write text
in a single line.

Does anybody else also experience this behavior?

Best,
Claus
