Sort Out the Standard Toolbar and Formatting Toolbar
The Problem:
The Standard toolbar and Formatting toolbar have decided to share a row and to each hide half their buttons.
The Solution:
Choose Tools 
Customize, click the Options tab, check the "Show Standard and Formatting toolbars on two rows" box, and click the Close button. In Word 2000, this option is implemented the other way around: the checkbox is called "Standard and Formatting toolbars share one row," and you need to uncheck the box.
