By the way, the client crashes when running at normal priority. Later I will test it again in low priority and on another dual core machine, the AMD64 X2 3800+. Tomorrow I can test it on the intel 2.8 GHz dual-core machine and on the P4 3.0Ghz HT.

I was twiddling with some of the internal array parameters. I may have
set an array size too small. This might be causing your crash.

I think it is amazing (and terrific

) that two instances running show only
about a 10% slowdown per process over 1 instance running. I expected
a lot worse.

Note that the 2Ghz Athlon showed about a 30% improvement over my
laptop. This is in good agreement with their relative clock rates.
