TI-85 tracer fails to show coordinates

I have a student with a TI-85. When she graphs a function and brings up
the tracer, the coordinates are *not* displayed at the bottom of the
screen. Other than that, the tracer seems to be working fine.


She claims that she only noticed this problem with the tracer after
loading the ZShell program and a bunch of games under ZShell. Could there
be a corrolation? I know nothing about ZShell.


Any help in getting her tracer to work again would be appreciated. Thanks.
