I don't know why this never occured to me before. After you finish your chapter and get ready to edit it, change the font first.

I use open office, and the default font is Times New Roman. So I use TNR out of habit. *shrug* When I changed the text to Helvetica by accident yesterday, I was able to see a lot of my mistakes instantly. Periods that should be commas, skipped words, extra spaces between words, autocorrect screw ups, etc. I think it works because, you're so use to seeing your own words one way, that when you make it look different, it REALLY looks different. That is my theory.

Carry on.
