OfficeLnFs is a package contains 'Microsoft Office XP' and "Microsoft Office 2003" Look and Feels for Java Swing applications. These Look and Feels require a JRE running on Windows XP.
The changes in beta-7 include:
1. Fixed a bug where toolbar buttons and other widgets on toolbars didn't have their backgrounds set to not-opaque.
2. Fixed a bug where menus inside of other menus didn't have their preferred widths calculated correctly.
