It's been some time since we last checked in with Rainmaker Research's system-wide spell-checking utility Spell Catcher X [1], but the longstanding program is alive and well, having recently been updated to version 10.3.3. Changes include compatibility with Snow Leopard, support for 64-bit applications, expanded import capabilities, additional preference settings, a new German localization, and auto-save capabilities for reference documents. Version 10.3.3 also includes the latest Proximity Linguistic System (which ensures the program is drawing from up-to-date spelling databases), enhances DirectCorrect and program launch performance speeds, and tweaks the program code to improve handling of documents and error reports. A full list of changes [2] is available on Rainmaker's Web site. ($39.95 new, free update, 22 MB)
