Continuity mistake: In the scene where Dick is buying a laptop, you can see that while the computer is on his lap, it is not really on. (00:06:40)
Factual error: Mary gives Dick directions to press Command-Q to close something. As Dick is using a Compaq computer which would be running Windows, he would not have a Command key and would instead have a Control key (which he actually is pressing) as the Command key exists only on Apple Macintosh computers. Ctrl+Q on a Windows machine doesn't do anything. (00:09:10)
Revealing mistake: In the scene with www.planetsolomon.com, you can see that it is a pre-filmed video (not a live stream as he said), as it has a time slider and play/pause controls etc. (00:13:05 - 00:13:45)
Suggested correction: During streaming, any video player can be used. Meaning "play" or "scroll" buttons are still visible, just not functional.
The color of non-functional buttons will be muted. You can see in the picture that the stop button is solid black, indicating that it is functional. The marker on the status bar is also partially advanced. In a live stream, the marker would remain at the beginning position unless someone paused the stream, in which case resuming play would cause the marker to advance in order to catch up to the delay. In this scene, Dr. Solomon is teaching his class and interacting with his students, meaning no-one paused the stream.
