Stairways Software has released a minor maintenance and stability update to the popular macro utility Keyboard Maestro. Version 4.0.1 resolves an issue that caused slow typing speeds when simulating keystrokes, fixes a bug that enabled multiple engines to run at once, prevents simulating keys from causing hot keys to trigger, and addresses a crashing bug that affected users running Mac OS X 10.5. Also, support for Growling macro execution has been added, the Remap Forward Delete macro is now disabled by default, and a 10-second emergency timeout has been added on trigger repeat. ($36 new, $18 upgrade from 3.x, free update, 7.6 MB)
