Define browser extension

I uninstalled something somewhere along the line and lost my Define browser extension. I wrote a new one to take its place and figured I'd share it. I use it most often as a simple spell-checker.

It works like the other IE extensions I've posted before. (Google It, DayPop Links, and Add Link Titles.) After installing, a new entry will appear in the right-click context menu of Internet Explorer called Define. Then you can highlight any word on a web page, right-click, choose Define and a new window will open with that word's definition at m-w.com. When I lost it, I kept using Google It instead, but it isn't quite the same when you're looking for the definition.

Define Setup
(right-click, Save Target As..., click to install. Windows only.)
