For some reason, when I try to do a computation in a fresh kernel, MM remembers the "old" values from the old kernel, is there a way to stop this?

    $\begingroup$ You have to give some more information. Can you give an example of an old value that is remembered on a fresh kernel? $\endgroup$

    $\begingroup$ Also, are you sure that you are shutting down the kernel, not just closing the notebook? I.e. does the problem persist if you use Quit[] to quit the kernel? $\endgroup$

  • $\begingroup$ @JasonB. An example is the last question I posted here about solving a ODE system. When I copy the symbolic expression(without the numerical values substituted) in a fresh kernel, it gives me the output from the old kernel(where I inputted the numerical values) $\endgroup$

  • $\begingroup$ @Hausdorff I haven't tried. however I still need the "old" notebook open so I'm not sure how this will work? $\endgroup$

    $\begingroup$ @Math - to quit the kernel but leave the notebook open either evaluate Exit[] or use the menu Evaluation -> Quit Kernel -> Local $\endgroup$
