Yeah, I was wrong when I thought I tested this--it doesn't do short
second references. Use Help | Send Feedback in Word to report it--keep
it mind that you need to explain the problem to people who do not use
footnotes, so give an example of what should happen and what happens
instead. I'd rather you didn't ask for Ibid, though, I personally don't
like it and it is no longer required--I think short titles work better.
But failing to use shortened second references is inarguably a bug.
You can use Find and Replace to quickly change the notes--put the cursor
in the footnotes first, and then Replace All *should* only apply to the
footnotes, but even clicking Replace a bunch of times is much faster
than manually changing it.
Me, I'm just sticking with Word 2004 and EndNote. But Bookends is
already supporting Word 2008.
