I've noticed quite frequently that when I go to the archive viewer, I'll have a long blue line of 'activity' but anywhere I click in that line, the video is frozen (and the timestamp on the actual video is stuck). If I go to the calendar view and move to the latest recording, it gets stuck at the beginning of the blue line.
Attached an image showing what I mean. What is going on here? I just upgraded to the new beta to see if it fixes anything, but it doesn't.
