Well Guys
I use an IE add-on called IE Spell, available from here:
http://www.iespell.com/
A nifty little utility adds spell-checking options under IE's Tool Menu. In addition, it works quite well.
I only have a couple of small criticisms:
1) The spelling is US orientated, e.g. It will have US spelling "realize" and not the UK spelling "realise", "color" and not "colour".
But, like most checkers, you can add to the built in dictionary.
2) A (very) few words in the checker are spelt incorrectly, but as before, you can add to the dictionary.

PS. It's well worth the price (free).
