Scrivener Crashing? Or is this a feature?

Every time I close a document, scrivener crashes - or does it quit because this is a feature? I’m using the 2.3.1 update on Mountain Lion. Oh, and I’m using the version of Scrivener from your site, not the app store version.

Actually, it must be crashing. I just went through the preferences to make sure there wasn’t a “quit when closing document” checkbox. When I closed the prefs window, Scrivener crashed. Or quit? I’m not getting any indication that it crashed, so I have to assume it’s just quitting. But why?

I wonder if this might have something to do with it:

However, if I were you I would simply reinstall Scrivener. It’s quite possible for something to go wrong with the installation and cause problems.
