I've been using LaunchBar for a long time, and have upgraded to each new release with no problems. But somewhere a few releases ago (I'm thinking 4.0.x) I noticed that the LaunchBar window stays visible on startup even though I have always had the Prefs set to hide it. I have to open LaunchBar prefs, select "Hide and show the bar automatically", and save prefs. But the next time I restart the Mac, the prefs have reverted to the default setting. I've tried removing the prefs files but that didn't help. Did I miss a file?
