ERROR: Lost atoms: original 62880 current 62881 (thermo.cpp:385) and dynamic load balancing confusion.

I can't reproduce your problem with the current version. You are using
an older version b/c

a) your balance command syntax is not current
b) when I run restart2data on your file, I get image flags with -512
    which means the syntax of the restart file has also changed

So I think if you rerun your simulations with the current version,
things will be fine. I do not see lost atoms with either input file.

Dear Steve,
I was using Feb12 version. I will try them out with latest version and hopefully things will be OK.
