There's nothing like real-world usage to flush out the last few bugs, as evidenced by the quick update to Keyboard Maestro 4.3.1, which fixes potential crashes when executing AppleScript or shell scripts, and when using device triggers. A few other minor bugs have also been fixed, and Stairways Software also added support for naming more X-Key keyboard keys and improved handling of negative numbers in the Move Window action. Full release notes are available. ($36 new, free update, 9.1 MB)
Fixing Save as Adobe PDF Crashes
There have been many reported instances of the "Save as Adobe PDF" workflow crashing regardless of application, but precious few workarounds or resolutions. In troubleshooting, I discovered that there were three instances of the "Save as Adobe PDF.action" in three different locations: /Library/Automator; ~/Library/Automator; and /System/Library/Automator. By eliminating all except the version in /System/Library/Automator, the workflow started behaving, and I was able to cut PDFs directly from the Print dialog.
