Remember the big "DHCP Vulnerability" that was supposed to prove that OS X machines were as security-bug prone as Windows? John C. Welch (as linked to by John Gruber) respondes with some knowledge from the Windows side of things.

Macscripter has a link to XSpell, a Scripting Addition that allows you access to the Mac OS X spelling system [macscripter.net]

The OS X built-in spelling system is very cool, and most of the time beats any other spell checker installed on my system for correcting my misspellings. I just wish Carbon applications could access that neat system API.
