After a lot of debugging and head-scratching, I've finally tracked down the tricky little error that was causing that strange crash-on-quit in Sweet16. Version 3.0.2 is now available to correct the problem.
In addition, this update adds a "Clear all breakpoints" option to the debugger, as well as improved code signing to make Mac OS X just a little bit happier.
On the interior front, I've updated the project to build with Xcode 5, so I'm ready to continue work on the stuff I'd already been doing toward the next major update. Check out the release notes and/or download Sweet16 3.0.2 now!
Enjoy!
