Lightbulb moment.

Health and safety course continues (working from home). Starting to feel a bit better, though the coughing and runny nose continue at the same pace. We're supposed to keep our microphones open all the time, but I'm sparing everyone else from near continuous interruptions.

Computer worked much better today, which was good, aside from any video clips that would go way out of sync and delay the appearance of further presentation material. Only breaks seemed to clear those delays.
