I am going to kill word '08?

Okay, I give the F*** right UP! I have been forced to use Word ‘08 by many, many, people. I don’t mind it so much, that is until I get one of my documents back with Tracked Changes.
I am currently writing a novel with my best friend, we both write and we both edit each others work. We both use the “Track Changes” feature Word and Pages has, however when I use Pages, her computer can not see them, so I have to use Word.
Alright, now I am just ranting: I am wondering if there is some way to set the default size of the text in the comment notes, or bubbles, or whatever you call them.
I can’t read them unless I use Mac’s built in zoom and it is getting really, really, damn annoying.
