Look, I know that it is a WIN NT file. My point is that all the programs
including Fritz get managed by this executable. The point of the blocks of hash
being in powers of 2 is valid but here is an example. Shredder allows 96 Mb for
a hash tabele. That is one of the settings. However it refuses to run with that
setting om my 144Mb RAM machine. Surely I have enough extra RAM to accomodate a
96Mb hash table, but I can't Shredder won't take more than 48Mb plus 8 Mb  more
for the pawn hash table. There are many other examples of programs swapping when
hash tables are chosen that are more than 50% of the total.
Tom Kerrigan hasn't addressed this issue.
