There is no Office Shortcut Bar in Office 2003. You can install
the OSB from a previous version of Office if you still have it.
See
http://support.microsoft.com/?kbid=822573 "Office Shortcut
Bar is not included in Office 2003" for other suggested workarounds.
To install only the OSB from a previous Office version, insert
the CD and choose a custom installation, click on the little
black downward-pointing triangle to the left of "Microsoft
Office" and set it to "not available", click on the + next to
"Office Tools" to expand the category, click on the triangle to
the left of "Office Shortcut Bar" and set it to "Run all from
computer", and OK your way out.
