[ODE] Re: Deterministic simulation on multiple clients

I have now tested to run the same simulation on one computer. This gives 
the same result every time, until I restart the computer. Then it starts 
to give a different result. Altough I haven't looked at it in detail, it 
looks like the divergence starts happening after the first collision (as 
Victor mentioned in the other thread). Now the question is what may 
change after a computer is restarted? Perhaps some RNG is seeded with 
the start time of the machine. Perhaps it has something to do with when 
DLL-files are loaded (do they stay in memory between program runs?).
