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
