How can I disable scratch preview window?

Question

While coding Python, I like Vim\'s omnicompletion function, but I don\'t want Scratch Window to pop up at top.

How can I disable it?

(I\'m using gVim 7.3)

If you don't mind the preview window too much, but want to easily close it, you can use the :pclose command or CTRL-W z keyboard combination see :help :pclose.
