I've just upgraded to IntelliJ IDEA 10, and it has started doing something extremely annoying. While writing documentation in a .txt file it has started giving me word suggestions as I type. This is, instead of helping, just irritating me while also consuming system resources. I haven't been able to find a way to turn this off in the Settings window. Perhaps there's a way of telling Idea not to do this for certain file types or in code comments?
Cheers,

Goto Settings->Editor->Code Completion and untick Autopop code completion in (ms), or if you set this to something like 1000, then it give you time to carry on typing before poping up.
