Frederic, the pop up that Jeroen mentioned is probably supposed to be the old tablebase engine, which appears to be gone in the newer version. Was on display in the "old" CB7 labelled as "start CD ROM 1-4" or smth similar. At least that's what I think. And, BTW, you seem to have a very mentalistic representation of what goes on when you start your CB8. It simply cannot start the analysis by itself unless there is an engine running in the background. You seem to have apportioned way too much to some "deus ex machina" inside CB8... but that is exactly what I do and accounts for much of our seemingly inexplicable attachment to computer chess. You know, the childish image of little men doing the thinking and playing chess :) "The whirring and probing" that I mentioned was only a metaphor -- my HD, which is a paltry 15 gig, does not whirr or probe either or I can't hear it... *** Djordje
