OO.org/Neooffice question about text suggestions

Hi I use neooffice and I was wondering
I've been getting annoyed at this little "feature" in which when you are typing a word that you have typed before, the app trys to complete it for you. However, this can get annoying when it guesses wrong and things keep popping up on the screen and you lose your train of thought.

How can I turn this off? I searched the Neooffice help and scoured the Writer preferences but didn't find anything.

Thanks.

 

thanks so very much now i can write my paper in peace
