I turned off spell check in Google Chromes options but it still underlines text in red.
How do I resolve this?

In latest Chromium Version 25.0.1330.0 (168471) I have a weird bug, it's checking my spelling though I already disabled it several times, looks like it's only checking other languages than English, and then it checks email addresses too.
Is there any temporary solution for this? Maybe a command switch to shortcut or something?

The wrench is now ... well, people are calling it a "hot dog" icon (googlechromereleases.blogspot.com/2012/08/beta-channel-update_23.html), but I always recognized it as representing a list of things. A stack of three horizontal bars with rounded ends.

PS to previous comment: Except now, in step 3, it just says "language settings". No spell checker settings. No way to turn it off. Screw that, I'm going back to Firefox.

Thank you so much. This has been bothering me for a long time!
