I have a question about my Mathematica6 on a windows machine. Say, I do a certain calculation with some defined values of constants, and it gives me an answer. Then, if I change a certain constant and run it again, it does not always re-do the calculation. It keeps giving me the same response.
I have to restart the whole application to get thing working again.
Is there something I need to do before re-running it? I have tried saving it before running. it does not always help.
Thanks a lot for your time.
