There are a few spell checkers available on the Internet and a search in Google will find some. This one does work with PAF notes. It's called FreeSpell and is available for a free download from: http://hcidesign.com/freespell/http://hcidesign.com/freespell/ This is what is stated about the program on the website: [QUOTE] FreeSpell is a spell checker for any and all Windows applications.You can use it in Eudora, in Microsoft Outlook, Symantec Visual Cafe, and even in Windows Explorer when renaming files (though it's a little tricky to do that). Anything that supports the clipboard supports FreeSpell, and all it takes is a hotkey to invoke it. Just as important, FreeSpell is based upon the Aspell engine, which means it offers the best spell checker around for people with weak spelling skills (as well for people who just need a quick proofreader). Aspell is full featured as well, with a large default dictionary, and custom dictionary support. [END QUOTE] Please address any queries about the program to the developer, as I currently don't have the program installed.
