Maybe it‘s a problem of 10.11 beta, but I’m observing this:
About 4 out of 5 times when I launch the KM editor it quits the engine. When this happens I see the beachball for a couple of seconds at KM launch, before the GUI becomes visible. In the cases where is does not kill the engine it launches without beachball.
Engine and editor are both checked in Accessibility. System reboot doesn’t help.
I can’t tell when I first saw this behavior; maybe since the 10.11 GM (15A282b) or since KM 7.0.1, or out of the blue, I don’t know.
