I am using CA x17 on a Dell XPS with Nvidea 4080. I try and perform any task and CA, for lack of better terms, ignores it. I try and delete, it highlights and when I hit delete, it does not delete. I try adding a cad line, it shows it until I release the mouse key and then it disappears. Add sollid, nope, add or delete anything does not work. I restart software and computer, it works for about 10 or 15 commands, then it starts back up with these games. Any suggestions would be greatly appriciated.
