Apostrophe spacing in Outlook 2007

[Elfman42]

We've recently upgraded users to Office 2007. One of my users is having an issue with new messages in Outlook. When typing in the body of a new message, contracted words are getting spaces being put after the apostrophe. A word like "can't" when typed, winds up appearing "can' t". The moment the apostrophe is typed, the cursor jumps forward several spaces.

The guilty element? It appears to be the "Notebook" stationary she's using for her messages. I changed it to nothing and then to a couple of other styles, and the spacing after the apostrophe didn't occur. I changed it back to notebook and voila, typing an apostrophe results in spaces being inserted before the next typed character.

Any ideas as to why this might be?

Cheers!
