Hi campsite:
Another alternative if you do not need this feature very often and you don't
like adding-on to your list of programs is to open a blank doc in a
full-featured word processor you already have and then cut & paste your text
there to do a spell check. then simply cut & paste back to the word pad.
This may require re-establishing a few hard page breaks, etc. but will work
just fine with a little practice.
