How to permanently expand drop-down menus:
In Word, Outlook, or any other program in the Office suite, from the Tools menu, select Customize, and then click the Options tab.
In Office XP or 2003, under "Personalized Menus and Toolbars", check Always show full menus, and then click Close.
In Office 2000, under "Personalized Menus and Toolbars", uncheck Menus show recently used commands first, and then click Close.
If you make these changes in one program, the changes will affect all the others in the suite: Excel, Word, etc.
