Deflate Comment Balloons
The Problem:
I use the Comments feature all the time. It worked fine in Word 2000, but it Word 2003 it drives me nuts. In Word 2000, the comment appeared in a pop-up balloon above the word to which it was anchored. When you printed the document with comments, they appeared on a separate page at the end of the file. In Word 2003, when you add a comment in Print Layout view, Word reduces the zoom level and creates a wide right margin where the comments appear. This makes it harder to edit the textand when you print, the whole page image is smaller, so it's hard to read, too.
The Solution:
Word XP offers the same annoyance. To stop Word from using right-margin balloons for comments and tracked changes, choose Tools 
Options, and click the Track Changes tab. In Word 2003, choose "Never" in the "Use Balloons (Print and Web Layout)" drop-down list. In Word XP, uncheck the "Use balloons in Print and Web Layout" box. Word then displays each comment in a balloon when you hover the mouse pointer over the text to which it's connected, as in Word 2000.
If getting rid of the balloons altogether is too drastic, use the "Preferred width" setting on the Track Changes tab to reduce the amount of space Word uses for the balloons.
