Howdy,
At the end of the installation process, if you’ve checked “Launch Scrivener” as you click Finish, it doesn’t.
This isn’t much of a problem, but it’s something that’s not working as it should so I guess that makes it a bug. It may also become an annoyance to some people – especially if they assume it means the installation has failed.
Opening the Read-me seems to work fine, though.
Have fun!
