One of my fellow workmates at MBAM found this nice IE spell checker, called speckie.
Ever since Internet Explorer was created, it has lacked an essential feature; real time spell check. Versoworks proudly brings you that feature, say hello to Speckie! The first and only dedicated real time spell check for IE. Download your FREE copy now. Check it Out
And their support is great. I found a bug adding words to the dictionary that had capitals in them and they got back to me in extremely short fashion and said the next version will have the issue corrected.
I replaced IESpell which had become kinda buggy, not checking all fields and leaving me with many typos. My typing sux.
