I've produced an experimental OSX app bundle. I can't test it myself, so I'd appreciate it if anyone could give me some feedback. It's in a zip because the Maven app bundle plugin can only produce .dmg format when running on OSX.

In particular, I'm curious if running it this way fixes the problem Tweety reported with databases not being closed. I think the problem is that on OSX, window closing events aren't properly transmitted to Java and so the window closing handler never runs to cleanly shut down the app.

If you can produce the step's to recreate the issue I can test it on Mountain Lion.

1. Start Weapon M.
2. Create a database.
3. Exit Weapon M by closing the window.

If the database lock file still exists (filename.wmd.lock) then the bug was triggered. The lock file is supposed to be deleted on exit.
