Update: I have now observed the same problem on multiple Macs.
I have installed and used Mavericks and Launchbar on 7 separate Macs. Three of those Macs were basically out-of-the-box fresh, with hardly anything else running of installed. In all cases, LaunchBar responsiveness was obviously impaired until I enabled the “Prevent App Nap” option for the App (via Get Info in Finder). In all cases, there were unambiguous examples of LaunchBar failing to register keystrokes, and then clearly and completely recovering when I turned off App Nap.
As long as the “Prevent App Nap” option exists, there’s no real problem here. But I’m worried and curious about the relationship between App Nap and OS X for the future.
