When you do the next spell check and it highlights a contraction, use the "Add to dictionary" button. It will take time, but that should do it.
I am using MS Office 2007 Home and student version, and running XP.
I am a writer (aspiring) and working on a novel. Spell check is great except for two things. It accepts some proper names and yet doesn't recognize others. Also it doesn't accept contractions: don't, can't it's, etc. Even when I select Ignore all, it doesn't. I get weary of seeing all the red lines where they shouldn.t be.
How can I fix this?
