I'm on the hunt for a free spell checking program. My options are either a small program I can have running in the dock, that I can paste text into, have it checked, then copy out and paste where-ever. The other option is a global spell checking type deal, that would check my spelling within Adium/Firefox/etc and let me change it there. I've already checked out 'Spell Catcher' (?!), but that cost money. Any ideas?
