After I resume my system (W2K) from a suspend to disk, the progess and CPU time jumps back to 0 % and the model begins again.
This only happens, if CPDN was running when I suspend the system to disk. There is no problem if a other project is running at the suspend, and CPDN is stopped.

This will happen if you don\'t give the model long enough to reach a check point, which is where it saves some restart data.
In which case, the only restart point is at the beginning.

Check points are once per model year.
If you click \"Show graphics\", then Z to get rid of the top layer of info, then 8, you\'ll see a countdown time. Once this goes back to the 400\'s, you\'re past the check point. The 8 key is a toggle.
