If you want to view the styles drop-down as it was in Word 2003, you can do
the following:
-Click the Office button
-Click Word Options
-Click Customize
-Scroll down to Styles (the one with the dropdown arrow next to it)
-Click the Add button
-Click OK
You will then see the Styles dropdown in the Quick Access toolbar at the top
of the page.
Hope this helps - I was psyched when I finally found it!
