Hi Peter,
1) Unfortunately sometimes WbNimzo2000 will hang up after the last book move or
it will even play an immediate blunder move which looses a piece at once. This
is due to an error in the synchronisation between the Nimzo winboard process
and the Nimzo engine process.
2) The wrong entries of book moves - i like to call them phantom moves - are a
long known problem and are due to a errorneous code in book lookup.
This can happen time to time.
From personal experience with the winboard version of Nimzo 7.32 which i
internally use for testing purposes i know that 1) is still a problem but i do
not know about 2).
Either way i do not see how to help you, because there are no plans to release a
new winboard version of Nimzo.
Greetings
Alex
