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!
