I've noticed that when Sonar crashed on me recently, it no longer asks me if I want it to attempt to save a recovery version of the project? Also it doesn't offer to send a notice to the developers anymore (although that was useless function). I wonder if these were removed.
I don't mean an Autosave file. That still works, thank goodness. An autorecovery file looks like this:
25 or 6 to 4.cwp.~2010-08-12-12-11-07-747
