It turned out that item 1 was the solution. Thanks to the many people who pointed this out, including Wolfram Tech Support: > This is a bug in Mac OS 8.0 and 8.1. Please see > http://www.wolfram.com/support/Systems/Macintosh/Compatibility/80.html for > the related FAQ and patch. I also nuked the front-end cache, just in case it too was causing trouble, as I could see no harm in trying this.
