Hello all,

There seems to be a problem with making checkpoints in simulations with 
the current version in the CVS-repo.  I attached the stacktrace (taken 
from trying to make a checkpoint when running the HeatBugs3D demo).

It's just a java.io.NotSerializableException that pops up.  But the 
trace doesn't really show much more usable info to track the problem down.

Any ideas where it might go wrong?


greetings
Bruno
