It's been some time since we last checked in with Rainmaker Research's system-wide spell-checking utility Spell Catcher X, 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 is available on Rainmaker's Web site. ($39.95 new, free update, 22 MB)
Enabling Auto Spelling Correction in Snow Leopard
In Snow Leopard, the automatic spelling correction in applications is not usually activated by default. To turn it on, make sure the cursor's insertion point is somewhere where text can be entered, and either choose Edit > Spelling and Grammar > Correct Spelling Automatically or, if the Edit menu's submenu doesn't have what you need, Control-click where you're typing and choose Spelling and Grammar > Correct Spelling Automatically from the contextual menu that appears. The latter approach is particularly likely to be necessary in Safari and other WebKit-based applications, like Mailplane.
