I discovered today that Microsoft Office X “optimizes” your MacOS X fonts. Most of the time that isn’t a problem, but, if you have the slightest disk error, the Office X application doing the optimizing will corrupt a font, and nothing will ever work right again. The Finder will begin relaunching at random, apps will quit, and you’ll be logged out without warning.
A tip to all those who have Office X installed: back up your fonts before running Office X. Not doing so could mean spending an hour re-installing OS X.
