Computer Challenged

Though I started using a computer in 1978 with a Tandy 4K with a cassette drive; and over the years moved from the inital 8088 with floppy drive 5 & 1/4. I rely on my son who is has his degree in networking to fix problems. As with all on his field, they get upset when simple questions are asked. He shared that he was drafted at the college he works for to teach as basis starter course one evening. When he told all in the class to move their mouse to the bottom of the screen, on lady placed her mouse on the monitor at the bottom !
