Adobe has released Illustrator CS6 16.0.1 with a number of fixes to improve overall stability. The update resolves an issue with Illustrator unexpectedly quitting if you have only read-only permissions on the Preferences folder, ensures the Transform commands work as expected when using the Transform Patterns option, fixes the Save for Web command to correctly create images with specified dimensions, and more. Additionally, the new release should improve copying and pasting when working with a third-party clipboard manager. ($599 new, $249 upgrade, free update, 5.8 MB via direct download, release notes)
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.
