"Notice" Lecture Video and System Issue Update
Course: Introduction to Economics
Instructor: Professor Lee Minjeong
Date: October 30, 2025
Hello everyone,
During today’s online lecture, several students experienced an issue where the screen went black while the audio continued to play. It looks like this was caused by a browser compatibility problem after last week’s system update.
If you encounter the same issue again, please try opening the lecture site with a different browser (for example, Chrome or Edge). This should solve the problem in most cases. I’ve already reported the issue to the IT Center, and they are working to prevent it from happening again.
In the meantime, I’ve uploaded today’s lecture recording so that anyone who missed part of the class can review it.
