He is what Ed posted on the Rebel Board. ____________________________________________________________________________ Rebel lost. After 10 crashes the moves of the game are lost too. Rebel apparantly played with a wrong version. After 10 crashes I loaded the Sorin/Rohde version. No crashes since then but then it was already too late. I am sorry, it never happened in my whole life I played with a corrupted version. Expensive though! So most likely it was not the hardware. I have some homework to do!
