I'm gonna check that now

It looks like Oculus Rift SDK produces a deadlock because 2 instances of it are created (in launcher and client)

I'll see if I can do something about it.

It looks like to solve this problem first I would need to try and update Oculus SDK to latest version, this will happen in the future, so for the moment I recommend as a workaround calling "Exit()" in client app 'Shut' function.
