I took a three hour on demand ethics course and watched it in segments over two days but System glitched when seeking credits. Clicked on all interactive requests as they appeared on the screen and when seeking credit for course was advised by System that I had only watched less than a third of ethics course. I cannot devote time to watching on demand if the System glitches because the video is paused occasionally during the course of watching the entire program. The virtue of on demand is supposed to be the flexibility of watching segmentally between other daily practice demands.
