For the past few days about 1/3 of my class has been having issues with the cursor not correctly moving with the text they type. Unfortunately, I as the teacher am one of them. This is make it very difficult to type code and for the students to follow along. When I start a new line, the cursor moves correctly with what is typed at first, but the longer the line becomes the more the cursor lags behind where I am actually typing making it almost impossible to go back and edit a line because I cannot tell where the computer thinks I'm selecting verses where I actually click to select. I have been teaching this same class for years using Repl.it and never had this issue. Any help would be greatly appreciated!
