Weird Behavior- RoadHog 4 3.20 (b3569)

Instance one after programming 60-70 small plot cues rapidly the console locked up all input and desktop functions except playback which was fine. Instance two: Different show file:  when I powered up the console it powered up in blind. If I release blind a cue starts to playback. Nothing is in the programmer, no cues show as active. Pig release does not stop the playback. Hitting blind stops the playback. Nothing shows in programmer when in blind. Preprogrammed cuelists play back properly.  Does anyone have any guesses.
