Smoothing out the rough spots, RedleX has released Mellel 3.2.7 with several fixes to improve stability and performance. The word processor gets a fix for a crash that occurred with the Spotlight plug-in when trying to index template files, adds support for small caps in formatted citations and bibliographies, fixes a problem with non-functioning smart quotes in OS X 10.9 Mavericks using the Hebrew keyboard layout, avoids a crash when Mellel scanned documents containing empty citations, and fixes a problem with Bookends 12.0.6 that prevented live bibliographies from functioning correctly. As of this writing, the Mac App Store version remains at version 3.2.6. ($39 new from RedleX and the Mac App Store, free update, 97.7 MB, release notes)
Mac OS X Zip Expanding Utility
Firefox (and possibly other applications) may ask you what you want to do with .zip archives that you download from the Internet. If you want to expand them with Mac OS X (rather than StuffIt Expander), you may be unsure of which application actually does the job. You're looking for Archive Utility (in Leopard and later) or BOMArchiveHelper (in Tiger). In either case, the application is stored in Hard Drive/System/Library/Core Services/. Don't move it from there, though, or you'll confuse matters.
