Whenever I use any command like tan, tan radius for the circle or the break at point command and then when I finish using it I press enter to redo that command it will always change it to the first command on the list i.e. the center, radius command or the break command. It would be nice if instead of going to the first command when I press enter it would instead do the command I just used. I'm not sure if it is a bug or was designed to be like this.
