You are right :)

by the way I think I know why at some positions (during the game) fritz7 (and
other chessbase engines) dont use full cpu, only 2-3% and the rest of the
processor is idle, it probably because of the hash size.

Because when I checked the "task Manager" I see that the program is swaping alot
and using more memory then I specified, but this is in very rare position,
during the game in one or two positions.

I only used 128mb has but sometimes Fritz used way more than that
amount(300-350), and i dont know why. I have 512mb ram.

It might be some kind of bug, memory leaking of some short.
