I am doing a 40 game match at home at time control of 10 2 and so far no crashes overnight. The pondering is now off for both sides. When I come home from work, I will send you everything including the result. It looks like the crashes were because of pondering. Remember this is on a Pentium 166. -- Komputer Korner
