I just upgraded from 1.0.2 to 1.1.1 thanks to the excellent guides on modmyi.com

I noticed after upgrading that it doesn't auto-correct when typing the same way it did in 1.0.2

For example in 1.0.2 if you wanted to type "it's", you'd type "itsa" and "it's" would pop up. Now in 1.1.1. it doesn't seem to do that. you type "itsa" and "itsa" stays, not corrected to "it's".

Is it something from 1.1.1 or something I did?
