Hi ctacker!
It works just as good for me also, but I'm using Firefox as my browser because Internet Explorer has too many" leaks that hackers and virii exploit! ;)"
Ultimately none of the spell checkers are perfect either, so I rely on it primarily for checking words that have no more than two syllables, and when I type a word that I personally know is spelled correct, and yet there's squiggly lines underneath the word, I'll always fall back on the dictionary which is also Websters to verify, then flip a bird to the spellchecker when I notice it messed up!!! :) :) :) It's a nice tool to have but remember this, tools are not always made to be perfect always. ;)
Respectfully,
Henry
