I just crashed in a (completely) new way to desktop. I got my screen locked and when logging back in, I could hear ESO, but it's not found anywhere, not even in the process list ... as far as I can tell. I had to reboot the system.
Also, since a couple of updates, the eso.app can't be started standalone, which is a problem with security oriented systems. The launcher.app - eso.app sequence can only work, if launcher.app releases itself, after it started eso.app ... if this is the way you want it. It is not tolerable that one app is depending on another and does not release itself before the second one closes. I have made that clear several times. It's our computers!
