Give HN: Proofreading Bookmarklet that Works Here

I'm using it in Firefox 3.5.7 on Windows XP (behind a proxy server). A couple of observations:<p>* It flags spelling and grammatical errors but when I click on a fix suggestion for a grammatical error, it does not apply the fix.<p>* Browser slows down to a crawl while the proofreading bookmark is in operation.<p>Great concept; I would love to use it if you can address these issues.

Seems to be broken atm, clicking on the bookmarklet-induced icons gives 'No writing errors were found' no matter what typos or grammar mistakes are present. I'm guessing the back-end can't handle the load at the moment or something.

Seems to work well here. But I don't see how it didn't suggest "hello" as a possible correction of "helo"?

Safari here. Writing in this text area "its awesome" resulted in the green image.
