New version. Much faster.
ieSpell is a free Internet Explorer browser extension that spell checks text input boxes on a webpage. It should come in particularly handy for users who do a lot of web-based text entry (e.g. web mails, forums, blogs, diaries). Even if your web application already includes spell checking functionality, you might still want to install this utility because it is definitely much faster than a server-side solution. Plus you get to store and use your personal word list across all your applications, instead of maintaining separate ones on each application.

This program is great for checking the spelling of your keywords, comments and forum entries.
Simply right click in a text box you wrote in and select "Check Spelling" from the menu and it will take you through the list of misspelled words in the text and suggest correct spelling.
This program is a must-have if you use Internet Explorer. It's been around forever and now they have a new version after 4 years of no upgrades.
