While downloading the most excellent SpyBot Search & Destroy (Fantastic, excellent, wonderful, killer, recommended to friends and family, and all around great ap. Can you tell I really really like it?)I found this neat little spell script. When you highlight text in IE you can tell it to spell check. This fires up MS Word's spell checker and it goes through the text. The finished text is then put on your clipboard. Then just hit Ctrl-V and the corrected text replaces the highlighted text.
